(2) Operation timing in external event count mode
Cautions 1. In the external event count mode, the TPkCCR0 and TPkCCR1 registers must not be
(a) Operation if TPkCCR0 register is set to FFFFH
If the TPkCCR0 register is set to FFFFH, the 16-bit counter counts to FFFFH each time the valid edge of
the external event count signal has been detected.
