from 1 step to 255 steps (ARR=254 to ARR=0).
counter=4MHz gives a time base range of [250ns to 63.75µs]
fcounter=2MHz gives a time base range of [500ns to 127.5µs]
fcounter=1MHz gives a time base range of [1µs to 255µs]
fcounter=500kHz gives a time base range of [2µs to 510µs]
fcounter=250kHz gives a time base range of [4µs to 1.02ms]
PWMART_OCMP_Timebase
Void PWMART_OCMP_Timebase(double Tinput,double
Time,Pwmart_Clock SELECT_CLK)
Sets the output compare to be used as time base interrupt.
Interrupt is generated after every fixed (time base) inter-
val, depending upon the value of input parameter 2.
Tinput
You have to pass this value in nano-second (ns).
Tinput = 1 / Fcpu or
Tinput = 1/ Fext, in case of external clock.
Time
You have to pass this (time base) value in nano-second
(ns).

PR = 1,
PR = 2,
PR = 4,
PR = 8,

PR = 32, f
PR = 64, f
PR =128, f
where f
f
None
This function does not support floating clock (such as
5.33MHz).
None
1. You must enable the interrupt with instruction ‘rim’.
2. Interrupts are generated at the time base you provide.
