Section 10 16-Bit Integrated Timer Unit (ITU)
10.3.2
The registers other than the timer counters, general registers, and buffer registers 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.
