Changes in AVR Studio.

Comments and questions can be sent to avr@atmel.com

Version 1.21
============
Bugfix in Timers (Simulator): If the processor tries to write the value
of the timer in the same clock as the timer counts, the value written
by the processor will override. 

Bugfix in Timer 1 (Simulator): In PWM mode, the direction bit is reset so
so that the timer will always start counting upwards in PWM mode. Further,
the high bits (9-16, 10-16 or 11-16 depending on which PWM mode) are
cleared in the counter when entering PWM mode.

Bugfix in interrupt flags (Simulator): The flags which are cleared by
writing a '1' will now behave this way in the Simulator. In previous
versions, these flags were cleared by writing a '0'.

New feature: If an UBROF object file contains initialized data, a warning
will be issued on the screen since this will require that the system
has an external PROM which these initialized data are located in. 

Emulator problem workaround: The ICEPRO Emulator is currently facing
problems when trying to write to SRAM locations above address 0x1FFF. If
the user causes an SRAM write above 0x1FFF to the Emulator, a warning will
be issued the first time that the write is aborted and that subsequent
writes will be silently aborted.


Version 1.22
============
Removed problems introduced in version 1.21. There was an error in
reconstruction of breakpoints when reentering an object file. There
was also a problem when a new device was selected the first time an
object file was loaded into AVR Studio.


Version 1.25
============
New features:
1. Device support for ATmega103 and AT90S2323.  
2. Simulator support for new 8 bit timer, timer 0 and 2 for ATM103
3. New views for timer 0,2 and ADC for ATM103
4. Extended functionality in the watch view (pointer dereferencing)
5. Simulator support for EEPROM interrupt and WEE.

Bugfixes:
1. Clear counter on compare match for timer 1 corrected.
2. External interrupts did not get the interrupt flag set when the external interrupt was disabled. 
3. Debugging of UBROF assembly format files did not initialize the Simulator correctly. 
4. Incorrect setting of external interrupt flag for AT90S1200.  

Other changes:
1. Removed Download Configuration.  Supported in a separate program.
2. Port views disable unused pins.
3. When a new device is selected, views not supported by the selected device are removed.



Version 1.30
============

New features:
1.  Reload.
2.  Ubrof 6.0 support.
3.  Mega ICE Support.
4.  ASIC ICE Support. 
5.  Trace buffer support for ICE GA2.  
6.  8535 & 4434 support for ICE & Simulator. 
7.  Preliminary COFF support.
8.  Improved Register view. 
9.  Read only possible for .avd file.
10. Simulator warning.
11. Emulator HW and SW information.


Bugfixes:

1. Eeprom register view is OK. 
2. Eeprom write simulation is OK. 
3. AT90S1200 Timer 0 is OK. 
4. AT90S1200 External interrupt 0 is OK.
6. Configuration change do now reset AVR, OK.
7. Uart Status register RxC flag is OK. 
8. Breakpoint is now set on correct line, OK.  
9. Right adjustment in source view, OK.
10. AT90S1200 Eeprom write do now not require EEMWE, OK.
