Function Descriptions
Table 107. PWMART_Counter_Enable
Notes: To use PWMART as a timebase, use the following procedure:
– Depending upon the time base required, you have to calculate the value of Counter_Data to
– You can use PWMART_OCMP_Timebase function.

be loaded in ARR register. This value can be calculated from the following equation:
OR
Counter_Data = Timebase / Tcounter
where Timebase : time base required by user and Tcounter = 1 / fcounter
PWMART_Counter_Enable
Void PWMART_Counter_Enable(Pwmart_Counter
SELECT_REG,unsigned char Counter_Data,
Pwmart_Clock SELECT_CLK)
Initializes the PWM counter. You can select counter fre-
quency.
PWMART_REG_C
where C can be CAR or ARR
If C = ARR; Counter is forced to be loaded with ARR reg-
ister at each overflow, automatically and clears prescaler
register.
If C = CAR; Counter is loaded with CAR register on the fly
and clears prescaler register.
Counter_Data
Data to be loaded in ARR register or CAR register. Data
can be selected from 0x00 to 0xFF.
