Timers
The MCU has three built-in timers A, B, and C. The functions of each timer are listed in table 7.
Timer A
Timer A is an 8-bit free-running timer that can also be used as a clock time-base with a 32.768-kHz
subsystem oscillator. Timer A has the following features:
One of eight internal clocks can be selected from prescaler S according to the setting of timer mode
register A (TMA: $008)
In time-base mode, one of five internal clocks can be selected from prescaler W according to the setting
of timer mode register A
An interrupt request can be generated when timer counter A (TCA) overflows
Input clock frequency must not be modified during timer A operation
