Example 43-19: PWM Output Pin Mode Selection
Table 43-4 provides the PWM register functionality for the Independent Output mode.
Table 43-4: Independent Output Mode Register Functionality
Table 43-5 provides the PMOD<1:0> bits selections for the different topologies and configuration.
/* Select PWM I/O pin Mode – Choose one of the following output modes */
IOCON1bits.PMOD = 0; /* For Complementary Output mode */
IOCON1bits.PMOD = 1; /* For Redundant Output mode */
IOCON1bits.PMOD = 2; /* For Push-Pull Output mode */
IOCON1bits.PMOD = 3; /* For True Independent Output mode */
