* regression/tmr0_16bit/tmr0_16bit.stc regression/tmr0_16bit/Makefile
regression/Makefile.am : remove trivial STC file
* src/16bit-processors.cc src/14bit-registers.h src/uart.cc
src/gpsim_time.cc src/psp.h src/bitlog.cc src/16bit-registers.cc
modules/usart.cc gui/gui_symbols.cc gui/gui_profile.cc
gui/gui_src_asm.cc : Fix uninitialized variables detected by
valgrind

2011-02-17 Borut Razem
* plat/win32/gpsim.nsi: fixed bug #3151323: problem on start gpsim

2011-02-13 Rob Pearce
* src/p18x.h src/p18x.cc
Fixes to 18F6520 implementation: correct EEPROM size, remove spurious
wrong clock pin allocation, adjust structure to match style of 4x21 types

2011-02-12 Rob Pearce
* src/p18x.h src/p18x.cc src/pic-processor.cc src/pic-processor.h
Implemented the remaining devices from DS39689E (18F2221 & 4221) and
all devices from DS39631D (18F2420,2520,4420,4520)

2011-02-10 Rob Pearce
* src/p18x.h src/p18x.cc
Re-factored 18F2455 and 18F4455 to be derived from 2x21 and 4x21 so
they get the right Config3H and the right ADC, plus RE3/MCLRE pin

2011-02-03 Rob Pearce
* src/p18x.h src/16bit-processors.cc src/p18x.cc src/eeprom.h
Small re-organisation of how the EEPROM gets added to 18f2x21 and 4x21
derivatives. Some of the decisions pushed into the core classes so that
new CPU derivatives need fewer unique methods.

2011-02-03 Roy Rankin
* src/intcon.cc regression/tmr0_16bit/tmr0_16bit.asm
regression/ccp_628/ccp_628.asm :
+ tmr0 not waking after sleep (bug 3162315)
* src/ssp.cc : SPI and I2C may not start (bug 3169541)
* extras/rs232-gen/rs232-gen.c extras/rs232-gen/example/Makefile
extras/rs232-gen/Makefile : Update syntax (patch 3125817),
fix baud rate

2011-02-03 Rob Pearce
* src/p18x.cc src/p18x.h src/pic-processor.cc src/pic-processor.h
src/eeprom.cc src/eeprom.h
Initial implementation of PIC18F4620 for feature request #3159000
EEPROM_PIR class modified to support >256 byte EEPROM
Some re-factoring of 18F2x21 derivatives for less duplication
Config3H_2x21 class now implements PBADEN bit. Attempts to implement
CCP2MX bit too, but the CCPCON class doesn′t allow the pin re-allocation
Note: This would break the 18F2455 so its Config3H has been commented
until it is re-factored to be derived from the right base class!

2011-02-02 Rob Pearce
* src/cod.cc
Fixed addressing of memory on 16-bit cores while allocating HLL code
references. This was responsible for a crash with large programs / long
addresses found in 18F4620 development and bug #3154828, although it′s
not necessarily the only cause of that.

2011-01-03 Roy Rankin
* src/comparator.cc regression/comparator/compar_882.asm
regression/comparator/16f882.lkr regression/comparator/Makefile
regression/run_regression.sh : Fix for bug # 3150231
Polarity should not change when ON bit is off. Fix comparator
output pins cannot be driven from port when comparator is off.
Add regression tests.

2010-12-10 Rob Pearce
* src/14bit-tmrs.cc regression/ccp/pwm_6520.asm regression/ccp/pwm_877a.asm
Fix for bug #3132914 : The clocking of TMR2 should not be affected by
whether any of the CCPs are in PWM mode, and now it isn′t. Duty cycle
value is now handled correctly instead.

2010-11-28 Rob Pearce
* src/pic-ioports.cc src/intcon.h
regression/interrupts_16bit/interrupts_16bit.asm :
Fix for bug #3120903 : INT0 edge selection moved to the correct
register on 16-bit devices. Also fixed the regression test so that it
actually bothers to check which edge caused the interrupt.
Code for INT3 implemented but not tested yet.

2010-10-31 Rob Pearce
* src/16bit-instructions.cc src/pic-processor.h src/p18x.h
Partial implementation of "bugs" list (errata per CPU type) so that
the 18F6520 has a buggy DAW instruction while the 18F4321 has a
correct one. This matches the real hardware for those two - others
need checking.
* src/16bit-processors.h src/16bit-instructions.cc src/p18x.h
A different approach to fixing the compiler warning Roy spotted (I′d
already corrected my earlier error locally).

2010-10-31 Roy Rankin
* src/16bit-processors.cc src/intcon.h src/intcon.cc
src/pic-ioports.h src/pic-ioports.cc
regression/interrupts_16bit/priority.asm

- implement intcon3 for int1, int2 operation bug #3071596
* src/16bit-instructions.cc : fix complier warning

2010-10-25 Rob Pearce

2010-10-22 Rob Pearce
* src/14bit-tmrs.cc src/14bit-tmrs.h src/16bit-processors.cc
src/p12f6xx.cc src/p16f88x.cc src/p16x6x.cc src/p18x.cc
Fixed TMR2 to support multiple PWMs, bug #2823242
Implemented all five PWMs on the 18F6520
Fixed TMR2 wrap bug, #3092906
* regression/ccp/pwm_6520.asm regression/ccp/18f6520.lkr
regression/ccp/Makefile regression/run_regression.sh
Added regression test for the above

2010-10-08 Rob Pearce
* modules/resistor.cc modules/resistor.h
Minor fix to pulldown so that its resistance attribute is correctly
initialised to 0 (it was confused and showed as 5V)

2010-09-29 Rob Pearce
* src/p18x.h src/p18x.cc src/16bit-processors.cc src/16bit-processors.h
Fixed GPR memory size and SFR peripheral set of 18F1220 (the 16 bit
base class assumptions of portC and CCP2 are now optional)
* src/14bit-tmrs.h src/14bit-tmrs.cc src/uart.cc
Partial rework for >2 PWMs as on 18F6520, and multiple UARTs naming

2010-08-25 Rob Pearce
* src/p18x.h src/p18x.cc src/p16x6x.cc src/p12f6xx.cc src/p16f88x.cc
src/16bit-processors.cc src/16bit-processors.h src/pir.cc src/pir.h
src/pic-instructions.cc src/pic-processor.h src/16bit-instructions.cc
src/14bit-tmrs.h src/14bit-tmrs.cc
Implemented PIR3 for 18F6520, including the presence of multiple
CCPxIF flags in one PIR (needed some re-design)
Fixed implementation of 18F "access bank", as some devices have more
than 128 bytes mapped to SFR space

2010-08-21 Rob Pearce
* src/p18x.h src/p18x.cc src/p16x6x.cc src/p16f87x.cc src/p16f62x.cc
src/p16f88x.cc src/p16f8x.cc src/16bit-processors.cc
src/pic-processor.cc src/pic-processor.h src/uart.cc src/uart.h

linkage for multiple UART support.
