Description
Slave Select—This signal can be an output or an input. If the
is the SPI Master, this pin can be configured as the Slave Select output. If the

multiplexed with a GPIO pin.
SPI Serial Clock—The SPI Master supplies this pin. If the
the SPI Master, this pin is the output. If the
this pin is the input. It is multiplexed with a GPIO pin.
Master-Out/Slave-In—This signal is the data output from the SPI Master
device and the data input to the SPI Slave device. It is multiplexed with a GPIO
pin.
Master-In/Slave-Out—This pin is the data input to the SPI Master device and
the data output from the SPI Slave device. It is multiplexed with a GPIO pin.
Transmit Data—This signal is the transmit output from the UART and IrDA.
The TXD signals are multiplexed with GPIO pins.
Receive Data—This signal is the receiver input for the UART and IrDA. The
RXD signals are multiplexed with GPIO pins.
Clear To Send—This signal is control inputs for the UART. The CTS signals
are multiplexed with GPIO pins.
Driver Enable—This signal allows automatic control of external RS-485
drivers. This signal is approximately the inverse of the TXE (Transmit Empty)
bit in the UART Status 0 Register. The DE signal can be used to ensure the
external RS-485 driver is enabled when data is transmitted by the UART.
Timer Output 0–1—These signals are output pins from the timers. The Timer
Output signals are multiplexed with GPIO pins.
Timer Input 0–1—These signals are used as the Capture, Gating and Counter
inputs. The Timer Input signals are multiplexed with GPIO pins.
Analog Input—These signals are inputs to the Analog-to-Digital Converter
(ADC). The ADC analog inputs are multiplexed with GPIO pins.
Analog-to-Digital Converter reference voltage input—As an output, the
VREF signal is not recommended for use as a reference voltage for external
devices. If the ADC is configured to use the internal reference voltage
generator, this pin should be left unconnected or capacitively coupled to
analog ground (AVSS).
