Standard Timer Module
12.5.11 Timer Flag Register 1
Read: Anytime
Write: Anytime; writing 1 clears flag; writing 0 has no effect
C7F–C0F — Channel Flags
12.5.12 Timer Flag Register 2
Read: Anytime
Write: Anytime; writing 1 clears flag; writing 0 has no effect
132
These flags are set when an input capture or output compare occurs on the corresponding channel.
Clear a channel flag by writing a 1 to it.
Address: $008E
Address: $008F
The newly selected prescale divisor does not take effect until the next
synchronized edge when all prescale counter stages equal 0.
When the fast flag clear-all bit, TFFCA, is set, an input capture read or an
output compare write clears the corresponding channel flag. TFFCA is in
the timer system control register (TSCR).
