DTHSBUF - Dead-Time High Side Buffer Register
OUTOVEN - Output Override Enable Register
• Bit 7:0 - DTHSBUF: Dead-Time High Side Buffer
This register is the buffer for the DTHS Register. If double buffering is used, valid contents in this
register is copied to the DTHS Register on an UPDATE condition.
Note:
• Bit 7:0 - OUTOVEN[7:0]: Output Override Enable
These bits enable override of corresponding port output register (i.e. one-to-one bit relation to
pin position). The port direction is not overridden
