7.2.2 Timer A clock division select register

In the timer mode, one-shot pulse mode, and pulse width modulation (PWM) mode, the count source select

bits (bits 6 and 7 at addresses 5616 to 5A16, D616 to DA16), and timer A clock division select bits (bits 0 and

1 at address 4516) select the count source. Figure 7.2.3 shows the structure of the timer A clock division

select register. Table 7.2.3 lists the count source (in the timer mode, one-shot pulse mode, and pulse width

modulation (PWM) mode).

Each of timers A3 and A5 to A8 is equipped with the timer mode only.
