(3) Operation of interval timer based on input of external event count
(a) Operation
TPnCCR0 register
TPnCCR1 register
TOPn1 pin output
(TIPn0 pin input)
Remark
When the 16-bit counter is incrementing based on the valid edge of the external count input (TIPn0 pin) in
the interval timer mode, one external event count valid edge must be input immediately after the TPnCE bit
changes from 0 to 1 to start the counter incrementing after the 16-bit counter is cleared from FFFFH to
0000H.
Once the TPnCCR0 and TPnCCR1 registers are set to 0001H (that is, the same value as was previously
set), the TOPn1 pin output is inverted every two counts of the 16-bit counter.
Note that the TPnCTL1.TPnEEE bit can only be set to 1 when timer output (TOPn1) is used based on the
input of an external event count.
