To change the set value of the TABnCCRm register to a smaller value, stop counting once, and then change
the set value.
If the value of the TABnCCR0 register is rewritten to a smaller value during counting, the 16-bit counter may
overflow.
When the TABnCCR0 register is rewritten from D

compared with the count value. The counter counts up to FFFFH and then counts up again from 0000H.
When the count value matches D
pin. When the count value matches D
TOABnk pin, and stops counting.
Therefore, the counter may output a pulse with a delay period or active period different from that of the one-
shot pulse that is originally expected.
