By reading TM00, the count value can be read.
If M is set to CR000, the interrupt signal (INTTM000) is generated when the number of external events
reaches (M + 1).
Setting CR000 to 0000H is prohibited.
Usually, CR010 is not used in the external event counter mode. However, a compare match interrupt
(INTTM010) is generated when the set value of CR010 matches the value of TM00.
Therefore, mask the interrupt request by using the interrupt mask flag (TMMK010).
