Output Drive Strength Selection for Port C Bits — Each of these control bits selects between low and high
output drive for the associated PTC pin. For port C pins that are configured as inputs, these bits have no effect.
0 Low output drive strength selected for port C bit n.
1 High output drive strength selected for port C bit n.
Ganged Output Pin Select Bits— These write-once control bits selects whether the associated pin (see
Table
be controlled by the data, drive strength and slew rate settings for PTCO.
0 Associated pin is not part of the ganged output drive.
1 Associated pin is part of the ganged output drive. Requires GNGEN = 1.
Ganged Output Drive Enable Bit— This write-once control bit selects whether the ganged output drive feature
is enabled.
0 Ganged output drive disabled.
1 Ganged output drive enabled. PTC0 forced to output regardless of the value of PTCDD0 in PTCDD.
