(e) 16-bit timer counter 01 (TM01)
By reading the TM01 register, the count value can be read.
(f) 16-bit capture/compare register 010 (CR010)
If M is set to the CR010 register, the interval time is as follows.
Interval time = (M + 1) × Count clock cycle
Setting the CR010 register to 0000H is prohibited.
(g) 16-bit capture/compare register 011 (CR011)
Usually, the CR011 register is not used for the interval timer function. However, a compare match interrupt
(INTTM011) is generated when the set value of the CR011 register matches the value of the TM01 register.
Therefore, mask the interrupt request by using the interrupt mask flag (TM0MK11).
