Reference the tables below when configuring the PWM outputs:
Normal PWM
Function Register Description
Output Y2 Y4 Physical Output
Configuration Register MWnn24 MWnn30 Value = 1 for this mode
Frequency Setting Register 1 MWnn25
MWnn26
MWnn25
MWnn26
Range = 1 to 10000
ON Duty Setting Register MWnn27
MWnn28
MWnn31
MWnn32
Range = 0 to 100
Output Enable Flag MWnn36_0 MWnn36_1 Enabled when ON
