10.3.2
The registers other than the timer counters (TCNTS), general registers A and B (GRAs and
GRBs), and buffer registers A and B (BRAs and BRBs) are 8-bit registers. These registers are
linked to the CPU by an internal 8-bit data bus.
Figures 10.12 and 10.13 show examples of byte read and write access to a TCR.
If a word-size data transfer instruction is executed, two byte transfers are performed.
