DTHS – Dead-time High Side Register
DTLSBUF – Dead-time Low Side Buffer Register
DTHSBUF – Dead-time High Side Buffer Register
OUTOVEN – Output Override Enable Register
• Bit 7:0 – DTLS: Dead-time Low Side
This register holds the number of peripheral clock cycles for the dead-time low side.
• Bit 7:0 – DTHS: Dead-time High Side
This register holds the number of peripheral clock cycles for the dead-time high side.
• Bit 7:0 – DTLSBUF: Dead-time Low Side Buffer
This register is the buffer for the DTLS register. If double buffering is used, valid content in this
register is copied to the DTLS register on an UPDATE condition.
• Bit 7:0 – DTHSBUF: Dead-time High Side Buffer
This register is the buffer for the DTHS register. If double buffering is used, valid content in this
register is copied to the DTHS register on an UPDATE condition.
