MOTOROLA Enhanced Capture Timer 259
TFLG2 indicates when interrupt conditions have occurred. To clear a bit
in the flag register, set the bit to one.
Read anytime. Write used in clearing mechanism (set bits cause
corresponding bits to be cleared).
Any access to TCNT will clear TFLG2 register if the TFFCA bit in TSCR
register is set.
TOF — Timer Overflow Flag
Set when 16-bit free-running timer overflows from $FFFF to $0000.
This bit is cleared automatically by a write to the TFLG2 register with
bit 7 set. (See also TCRE control bit explanation.)
