Write: Anytime; writing 1 clears flag; writing 0 has no effect
TOF — Timer Overflow Flag
When the timer channel 3 registers contain $FFFF and TCRE is set,
TOF never gets set even though the timer counter registers go from
$FFFF to $0000.
When the fast flag clear all bit, TFFCA, is set, any access to the timer
counter registers clears Timer Flag Register 2. The TFFCA bit is in timer
System Control Register 1 (TIMSCR1).
When TOF is set, it does not inhibit subsequent overflow events.
Read:
Write:
TOF is set when the timer counter rolls over from $FFFF to $0000. If
the TOI bit in TIMSCR2 is also set, TOF generates an interrupt
request. Clear TOF by writing a 1 to it.
