15.9.6 Port DLC Control Register
Read: Anytime
Write: Anytime
The BDLC port DLC functions as a general-purpose I/O port. BDLC functions takes precedence over the
general-purpose port when enabled.
BDLCEN — BDLC Enable Bit
PUPDLC — BDLC Pullup Enable Bit
RDPDLC — BDLC Reduced Drive Bit
Freescale Semiconductor
1 = Configure I/O pins for BDLC function. BDLC is active.
0 = Configure BDLC I/O pins as general-purpose I/O. BDLC is off.
1 = Connects internal pullups to PORTDLC I/O pins
0 = Disconnects internal pullups from PORTDLC I/O pins
1 = Configure PORTDLC I/O pins for reduced drive strength.
0 = Configure PORTDLC I/O pins for normal drive strength.
