Reading from TCNT, TCSR, and RSTCSR: TCNT, TCSR, and RSTCSR are read by using the
same method as for the general registers. TCSR, TCNT, and RSTCSR are allocated in addresses
H'FF74, H'FF75, and H'FF77 respectively.
10.5.2
If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 10.8 shows this operation.
