H. 8-bit Auto-reload Timer for Software Time Base
This is an 8-bit auto-reload timer, which generates a periodic interrupt to the CPU.
The time interval is programmable:
The minimun interval (unit) = 1/ (F
clock
÷
1024),
the programmable interval = the minimun interval
×
(AUTOLOAD Reg. value +1),
the maximum interval = the minimun interval

I. Parabola interrupt generator
This is an 16-bit auto-reload timer, which generates a periodic interrupt to the CPU. The interrupt
period is programmable: the time base = 1/Fclock, the programmable interrupt period = the time base
×
([PARAH, PARAL] 16-bit Reg. value+1), the maximum period = the time base
