Chapter 6 Parallel Input/Output
Port A can be configured to be keyboard interrupt input pins. Refer to
(KBI)
6.3.2
Port B is an 8-bit port shared among the ATD inputs and general-purpose I/O. Any pin enabled as an ATD
input will be forced to act as an input.
Port B pins are available as general-purpose I/O pins controlled by the port B data (PTBD), data direction
(PTBDD), pullup enable (PTBPE), and slew rate control (PTBSE) registers. Refer to
I/O
When the ATD module is enabled, analog pin enables are used to specify which pins on port B will be used
as ATD inputs. Refer to
about using port B pins as ATD pins.
6.3.3
Port C is an 8-bit port which is shared among the SCI2 and IIC1 modules, and general-purpose I/O. When
SCI2 or IIC1 modules are enabled, the pin direction will be controlled by the module or function. Port C
has high current output drivers.
Port C pins are available as general-purpose I/O pins controlled by the port C data (PTCD), data direction
(PTCDD), pullup enable (PTCPE), and slew rate control (PTCSE) registers. Refer to
I/O
When the SCI2 module is enabled, PTC0 serves as the SCI2 module’s transmit pin (TxD2) and PTC1
serves as the receive pin (RxD2). Refer to
for more information about using PTC0 and PTC1 as SCI pins
When the IIC module is enabled, PTC2 serves as the IIC modules’s serial data input/output pin (SDA1)
and PTC3 serves as the clock pin (SCL1). Refer to
for more information about using PTC2 and PTC3 as IIC pins.
