10.3.2 8-Bit Accessible Registers
All registers other than the TCNT register, general registers, and buffer registers are 8-bit
registers. These are connected to the CPU by an 8-bit data bus. Figures 10.12 and 10.13 illustrate
reading and writing in byte units with the timer control register (TCR). These registers must be
accessed by byte access.
