Parameters
Notes
PWM_Write_Latch
writes frequency and duty cycle into the latch regi-
ster only. The values are enabled for PWM output with
PWM_Latch
only.
The value of
dutycycle
depends on the setting of the parameter
startvalue
from the instruction
PWM_Init:
•
startvalue
= 1: Set
dutycycle
to the value of the duty cycle.
•
startvalue
= 0: Set
dutycycle
to the "inverse duty cycle":
dutycycle
= 100% - duty cycle
The highest output frequency where the duty cycle can be still defined
in 1%-steps, is 500kHz.
