(e) 16-bit timer counter 0n (TM0n)
(f) 16-bit capture/compare register 00n (CR00n)
(g) 16-bit capture/compare register 01n (CR01n)
Remark n = 0:
By reading TM0n, the count value can be read.
If M is set to CR00n, the interrupt signal (INTTM00n) is generated when the number of external events
reaches (M + 1).
Setting CR00n to 0000H is prohibited.
Usually, CR01n is not used in the external event counter mode. However, a compare match interrupt
(INTTM01n) is generated when the set value of CR01n matches the value of TM0n.
Therefore, mask the interrupt request by using the interrupt mask flag (TMMK01n).
