Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
P = Programmable
r = Reserved bit
-n = Bit value at POR: (‘0’, ‘1’, x = unknown)
bit 31-16
bit 15-0
Reserved: Write ‘0’; ignore read
ODCx<15:0>: ODCx Register bits⁽¹⁾
If a port pin is configured as an output (corresponding TRISx bit = 0).
1 = Port pin open-drain output enabled
0 = Port pin open-drain output disabled
If a port pin is configured as an input, ODCx bits have no effect.
Note 1: Depending on the device, certain register bits or the entire register may not be implemented. Refer to
Table 12.1 for specific register and bit assignments.
