9S08SH Modulo timer sometimes doesn't reset

Hello All,


did anybody observe that the modulo timer isn't reliably reset by writing to MTIMMOD?


As far as I see, a write to MTIMMOD doesn't reset TOF if the write occurs during an overflow event.


Tested with a bus clock and /4 prescaler.


Any workaround?
