9.2.1
Timer A is an 8-bit timer with interval timing and real-time clock time-base functions. The clock
time-base function is available when a 32.768-kHz crystal oscillator is connected. A clock signal
divided from 32.768 kHz or from the system clock can be output at the TMOW pin.
Features
Features of timer A are given below.
178
Choice of eight internal clock sources ( /8192, /4096, /2048, /512, /256, /128, /32, /8).
Choice of four overflow periods (1 s, 0.5 s, 0.25 s, 31.25 ms) when timer A is used as a clock
time base (using a 32.768 kHz crystal oscillator).
An interrupt is requested when the counter overflows.
Any of eight clock signals can be output from pin TMOW: 32.768 kHz divided by 32, 16, 8, or
4 (1 kHz, 2 kHz, 4 kHz, 8 kHz), or the system clock divided by 32, 16, 8, or 4.
