Subject: | Re: [RFC v3 0/1] Implement AVR WDT (watchdog timer) |
Date: | Thu, 10 Jun 2021 10:30:49 +0300 |
1. Initial implementation of AVR WDT
There are two issues with this implementation so I need your help here
a. when I configure the WDT to fire an interrupt every 15ms it actually happens every 6 instructions
b. when I specify --icount shift=0 qemu stucks
changes since v1
1. correct RW or RW1C behavior is implemented
2. icount functionality is fixed
3. I still observe something strange, it takes AVR 150 instructions to simulate 15ms
changes since v2
1. use REG8 & FIELD macros to define registers
2. fixing ICOUNT behavior
*** BLURB HERE ***
