(3) Operation by external event count input (TIPk0)
External event count input
(a) Operation
To count the 16-bit counter at the valid edge of external event count input (TIPk0) in the interval timer
mode, clear the 16-bit counter from FFFFH to 0000H at the valid edge of the first external event count
input after the TPkCE bit is set from 0 to 1.
When both the TPkCCR0 and TPkCCR1 registers are set to 0001H, the TOPk1 pin output is inverted each
time the 16-bit counter counts twice.
The TPkCTL1.TPkEEE bit can be set to 1 in the interval timer mode only when the timer output (TOPk1) is
used with the external event count input.
