22.3.5.1
Setting Procedure
To start or stop counting, follow these steps:
(1) Set bits CSRC1 to CSRC0 and bits CDIV1 to CDIV0 in the PMCiCON3 register.
(2) Set bits PSEL1 to PSEL0 in the PMCiCON2 register and bits FIL and SINV in the PMCiCON0
register.
(3) Wait for four cycles of the count source.
(4) Set the EN bit in the PMC1CON0 register to 1 (0 to stop).
(5) Set the EN bit in the PMC0CON0 register to 1 (0 to stop).
(6) Wait for two cycles of the count source.
(7) Confirm that the ENFLG bit in the PMC0CON2 register is 1 (0 to stop). (The ENFLG bit in the
PMC1CON2 register is disabled)
22.3.5.2
Count Operation
In input capture mode, the counter counts from 0000h to FFFFh, and then returns to 0000h to
continue counting.
When the counter becomes 0000h after FFFFh, the CEFLG bit in the PMCiCON2 register becomes 1
(counter overflow) and stays 1 until the next measurement.
