(3) Operation of interval timer based on input of external event count
External event count input
(a) Operation
When the 16-bit counter is incrementing based on the valid edge of the external event count input (TIQ00
pin) in the interval timer mode, one external event count valid edge must be input immediately after the
TQ0CE bit changes from 0 to 1 to start the counter incrementing after the 16-bit counter is cleared from
FFFFH to 0000H.
Once the TQ0CCR0 and TQ0CCRk registers are set to 0001H (that is, the same value as was previously
set), the TOQ0k pin output is inverted every two counts of the 16-bit counter (k = 1 to 3).
Note that the TQ0CTL1.TQ0EEE bit can only be set to 1 when timer output (TOQ0k) is used based on the
input of an external event count.
