TIMERS
The 38C1 group has five timers: timer X, timer Y, timer 1, timer 2,
and timer 3. Timer X and timer Y are 16-bit timers, and timer 1,
timer 2, and timer 3 are 8-bit timers.
All timers are down count timers. When the timer reaches “0”, an
underflow occurs at the next count pulse and the corresponding
timer latch is reloaded into the timer and the count is continued.
When a timer underflows, the interrupt request bit corresponding
to that timer is set to “1”.
Read and write operation on 16-bit timer must be performed for
both high- and low-order bytes. When reading a 16-bit timer, read
the high-order byte first. When writing to a 16-bit timer, write the
low-order byte first. The 16-bit timer cannot perform the correct
operation when reading during the write operation, or when writing
during the read operation.

φSOURCE: represents the supply source of internal clock φ. It is the oscillation frequency of XIN input
in the middle- and high-speed mode, built-in ring oscillator in the ring oscillator mode,
and sub-clock in the low-speed mode.
Notes 1: Internal clock in the low-speed mode is the sub-clock oscillation/2.
Internal clock in the ring oscillator mode is the internal ring oscillator oscillation/8.
Except CNTR input, timer 1 and timer 3 count sources, the clock except system clock cannot
be used as the count source.
2:
φSOURCE can be selected as the timer X count source only in the pulse output mode.
Write “0” to the count source selection bit except in the pulse output mode.
