These registers can be read from in the same way as other registers. For reading, TCSR is assigned
to address H'FFA4, TCNT to address H'FFA5, and RSTCSR to address H'FFA7.
13.6.2
If a TCNT clock pulse is generated during the T2 cycle of a TCNT write cycle, the write takes
priority and the timer counter is not incremented. Figure 13.5 shows this operation.
