(1) 16-bit timer counter 0n (TM0n)
TM0n is a 16-bit read-only register that counts count pulses.
The counter is incremented in synchronization with the rising edge of the count clock.
If the count value is read during operation, then input of the count clock is temporarily stopped, and the count
value at that point is read.
Address: FF10H, FF11H (TM00), FFB0H, FFB1H (TM01)
