19.4.4
When rising edge or falling edge is detected while the timer CMTCH0C is operating, the value of
CMTCHnC (n = 0, 1) is captured in the corresponding CMTCHnT (n = 1, 0). Then the IEn flag in
CMTIRQS is set to 1 and the interrupt is generated when the IEEn bit in CMTCTL is set to 1.
Each channel timer overflowed after the timer is counting up at H'FFFF that is the value of
CMTCHnC (n = 1, 0). Then the IOn flag in CMTIRQS is set to 1 and the interrupt is generated
when the IOEn bit in CMTCTL is set to 1.
The 16-bit timer CMTCHnC (n = 1, 0) is initialized to H'0000 when the TEn (n = 1, 0) bit in
CMTCL is cleared to 0 or an input capture occurs.
