Subject: [RFC 0/1] Implement AVR WDT (watchdog timer)
Date: Sun,  2 May 2021 23:10:39 +0300	[thread overview]
Message-ID: <20210502201040.52296-2-mrolnik@gmail.com> (raw)
In-Reply-To: <20210502201040.52296-1-mrolnik@gmail.com>

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
