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>: PWMx 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).
