6.3.3
Port C is an 8-bit general-purpose I/O port with four pins shared with the KBI2 keyboard interrupt inputs
and four pins shared with the SPI.
Port C pins are available as general-purpose I/O pins controlled by the port C data (PTCD), data direction
(PTCDD), and pullup enable (PTCPE) registers. Refer to
information about general-purpose I/O control.
When the SPI module is enabled, PTC7 serves as the SPI module’s slave select pin (SS1), PTC6 serves as
the SPI clock pin (SPSCK1), PTC5 serves as the master-in slave-out pin (MISO1), and PTC4 serves as the
master-out slave-in pin (MOSI1). Refer to the
information about using PTC7–PTC4 as SPI pins.
Any of the port C pins PTC3-PTC0 can be configured as a KBI2 keyboard interrupt pin. Refer to the
Keyboard Interrupt (KBI) Module
interrupt pins.
6.3.4
Port D is an 7-bit general-purpose I/O port with one pin shared with the BKGD/MS function, one pin
shared with the RESET function, one pin shared with the IRQ function, and one pin shared with the TPM.
Port D pins are available as general-purpose I/O pins controlled by the port D data (PTDD), data direction
(PTDDD), and pullup enable (PTDPE) registers. Refer to
information about general-purpose I/O control.
The PTD0/BKGD/MS pin is configured for the BKGD/MS function during reset and following reset. The
internal pullup for this pin is enabled when the BKGD/MS function is enabled, regardless of the PTDPE0
bit. During reset, the BKGD/MS pin functions as a mode select pin. After the MCU is out of reset, the
BKGD/MS pin becomes the background communications input/output pin. PTD0 can be configured to be
a general-purpose output pin through software control. Refer to
Chapter 5, “Resets, Interrupts, and System
information about using this pin.
The PTD1/RESET pin is configured for the RESET function during reset and following reset.
