TIMERS
The 4282 Group has the programmable timer.
Programmable timer
The programmable timer has a reload register and enables
the frequency dividing ratio to be set. It is decremented from a
setting value n. When it underflows (count to n + 1), a timer 1
underflow flag is set to “1,” new data is loaded from the reload
register, and count continues (auto-reload function).

The 4282 Group timer consists of the following circuit.
Timer 1 : 8-bit programmable timer
Timer 2 : 8-bit programmable timer
These timers can be controlled with the timer control registers
V1 and V2.
Each timer function is described below.
