Figure 13.5 Accessing Operation of 16-Bit Register (between CPU and TCNT (16 bits))
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 13.5 shows an example of accessing the 16-bit registers.
