15.2 Control Registers
The following registers control the operation of the MCPWM module:
• PTCON: PWM Time Base Control register
• PTMR: PWM Time Base register
• PTPER: PWM Time Base Period register
• SEVTCMP: PWM Special Event Compare register
• PWMCON1: PWM Control register #1
• PWMCON2: PWM Control register #2
• DTCON1: Dead Time Control register #1
• DTCON2: Dead Time Control register #2
• FLTACON: Fault A Control register
• FLTBCON: Fault B Control register
• PDC1: PWM Duty Cycle register #1
• PDC2: PWM Duty Cycle register #2
• PDC3: PWM Duty Cycle register #3
• PDC4: PWM Duty Cycle register #4
In addition, there are three device configuration bits associated with the MCPWM module to set
up the initial Reset states and polarity of the I/O pins. These configuration bits are located in the
FBORPOR device configuration register. Please refer to Section 24. “Device Configuration”
for further details.
