9.3.1
The timer counters (16TCNTs), general registers A and B (GRAs and GRBs) are 16-bit registers,
and are linked to the CPU by an internal 16-bit data bus. These registers can be written or read a
word at a time, or a byte at a time.
Figures 9.4 and 9.5 show examples of word read/write access to a timer counter (16TCNT).
Figures 9.6 to 9.9 show examples of byte read/write access to 16TCNTH and 16TCNTL.
