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 15-12 Unimplemented: Read as ‘0’
bit 11-8 BLANKSEL<3:0>: PWM State Blank Source Select bits
The selected state blank signal will block the current-limit and/or Fault input signals (if enabled via the
BCH and BCL bits in the LEBCONx register).

1000 = Reserved
0111 = PWM7H selected as state blank source
0110 = PWM6H selected as state blank source
0101 = PWM5H selected as state blank source
0100 = PWM4H selected as state blank source
0011 = PWM3H selected as state blank source
0010 = PWM2H selected as state blank source
0001 = PWM1H selected as state blank source
0000 = No state blanking
bit 7-6 Unimplemented: Read as ‘0’
bit 5-2 CHOPSEL<3:0>: PWM Chop Clock Source Select bits
The selected signal will enable and disable (CHOP) the selected PWM outputs.
