bit 7 bit 0
bit 10 PWMPIN: MPWM Drivers Initialization bit
1 = Pin state at reset controlled by I/O Port (PWMCON1<7:0> = 0x00)
0 = Pin state at reset controlled by module (PWMCON1<7:0> = 0xFF)
bit 9 HPOL: MCPWM High Side Drivers (PWMxH) Polarity bit
1 = Output signal on PWMxH pins has active high polarity
0 = Output signal on PWMxH pins has active low polarity
bit 8 LPOL: MCPWM Low Side Drivers (PWMxL) Polarity bit
1 = Output signal on PWMxL pins has active high polarity
0 = Output signal on PWMxL pins has active low polarity
Note: See Section 24. “Device Configuration” for information about other configuration bits on this
register.
