Prescaler 12 (PRE12), Prescaler X (PREX), Prescaler Y (PREY)
[Address : 20
16, 2416, 2616]
The count value of each prescaler is set.
The value set in this register is written to both the prescaler and
the prescaler latch at the same time.
When the prescaler is read out, the value (count value) of the
prescaler is read out.
