The BDLC port DLC functions as a general-purpose I/O port. BDLC functions takes precedence over
the general-purpose port when enabled. Read or write anytime.
BDLCEN — BDLC Enable
0 = Configure BDLC I/O pins as general-purpose I/O pins. BDLC is off.
1 = Configure I/O pins for BDLC function. BDLC is active.
PUPDLC — BDLC Pull-Up Enable
0 = Disconnects internal pull-ups from PORTDLC I/O pins.
1 = Connects internal pull-ups to PORTDLC I/O pins.
RDPDLC — BDLC Reduced Drive
0 = Configure PORTDLC I/O pins for normal drive strength.
1 = Configure PORTDLC I/O pins for reduced drive strength.
Holds data to be driven out on port DLC pins or data received from port DLC pins.
PORTDLC can be read anytime. When configured as an input, a read will return the pin level. When
configured as output, a read will return the latched output data. Writes will not change pin state when
the pins are configured for BDLC output. Upon reset pins are configured for general-purpose high im-
pedance inputs.
