12.3.14 Interface with CPU
16-Bit Register: TCNT and GR are 16-bit registers. Reading/writing in a 16-bit unit is enabled
but disabled in an 8-bit unit since the data bus with the CPU is 16-bit width. These registers must
always be accessed in a 16-bit unit. Figure 12.5 shows an example of accessing the 16-bit
registers.
8-Bit Register: Registers other than TCNT and GR are 8-bit registers that are connected internally
with the CPU in an 8-bit width. Figure 12.6 shows an example of accessing the 8-bit registers.
