When TPnCCS1 = 1 and TPnCCS0 = 1 settings (capture function description)
When TPnCE = 1, the 16-bit counter counts from 0000H to FFFFH and free-running count-up
operation continues until TPnCE = 0 is set. During this time, values are captured by capture trigger
operation and are written to the TPnCCR0 and TPnCCR1 registers.
Regarding capture close to the overflow (FFFFH), judgment is made using the overflow flag
(TPnOVF). However, if overflow occurs twice (two or more free-running cycles), the capture trigger
interval cannot be judged with the TPnOVF flag. In this case, the system should be revised.
