8. 16-Bit Timer
8.3.2
The registers other than the timer counters and general registers are 8-bit registers. These registers
are linked to the CPU by an internal 8-bit data bus.
Figures 8.10 and 8.11 show examples of byte read and write access to a 16TCR.
If a word-size data transfer instruction is executed, two byte transfers are performed.
