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 as the
subclock.
• 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 is connected as the subclock).
271 Description amended
When performing TCF read/write access or OCRF write access
in 16-bit mode, data will not be transferred correctly if only the
upper byte or only the lower byte is accessed. Access must be
performed for all 16 bits (using two consecutive byte-size MOV
instructions), and the upper byte must be accessed before the
lower byte.
