TIMERS
The 4570 Group has the programmable timers and a fixed
dividing frequency timer.
G
Programmable timer
The programmable timer has a reload register and enables
the frequency dividing ratio to be set. It is decremented from a
set value n. When it underflows (count to n + 1), a timer interrupt
request flag is set to “1,” new data is loaded from the reload
register, and count continues (auto-reload function).
G
Fixed dividing frequency timer
The fixed dividing frequency timer has the fixed frequency
dividing ratio (n). An interrupt request flag is set to “1” every n
count of a count pulse.
