10.3 CPU Interface
10.3.1 16-Bit Accessible Registers
The timer counters (TCNTs), general registers A and B (GRAs and GRBs), and buffer registers A
and B (BRAs and BRBs) 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 10-6 and 10-7 show examples of word access to a timer counter (TCNT). Figures 10-8,
10-9, 10-10, and 10-11 show examples of byte access to TCNTH and TCNTL.
