Description
Master-In/Slave-Out: This pin is the data input to the SPI master
device and the data output from the SPI slave device.
Transmit data: These signals transmit outputs from the UARTs.
Receive data: These signals receives inputs for the UARTs and
IrDAs.
Clear to Send: These signals are control inputs for the UARTs.
Driver enable (DE): This signal allows automatic control of
external RS-485 drivers. This signal is approximately the inverse
of the Transmit Empty (TXE) bit in the UART Status 0 Register.
The DE signal is used to ensure an external RS-485 driver is
enabled when data is transmitted by the UART.
General-purpose timer outputs: These signals are output pins
from the timers.
General-purpose timer inputs: These signals are used as the
capture, gating, and counter inputs.
PWM High output.
PWM Low output.
PWM Fault condition input: FAULT0 and FAULTY are active
Low.
Analog input: These signals are inputs to the ADC.
ADC reference voltage input or internal reference output:
The VREF pin must be capacitively coupled to analog ground, if
the internal voltage reference is selected as the ADC reference
voltage. A 10 μF capacitor is recommended.
