Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-11 Unimplemented: Read as ‘0’
bit 10-8 PMOD3:PMOD1: PWM I/O Pair Mode bits
1 = PWM I/O pin pair is in the Independent PWM Output mode
0 = PWM I/O pin pair is in the Complementary Output mode
bit 7 Unimplemented: Read as ‘0’
bit 6-4 PEN3H:PEN1H: PWMxH I/O Enable bits
1 = PWMxH pin is enabled for PWM output
0 = PWMxH pin disabled, I/O pin becomes general purpose I/O
bit 3 Unimplemented: Read as ‘0’
bit 2-0 PEN3L:PEN1L: PWMxL I/O Enable bits
1 = PWMxL pin is enabled for PWM output
0 = PWMxL pin disabled, I/O pin becomes general purpose I/O
Note 1: The PWMxCON1 register is a write-protected register. Refer to Section 15.3 “Write-protected
Registers” for more information on the unlock sequence.
2: The reset status for this bit depends on the setting of the PWMPIN Configuration bit (FPOR<7>):
• If PWMPIN = 1 (default), the PWM pins are controlled by the PORT register at Reset, meaning they
are initially programmed as inputs (i.e., tri-stated).
• If PWMPIN = 0, the PWM pins are controlled by the PWM module at Reset and are therefore initially
programmed as output pins.
