Description
SPI Serial Clock. The SPI master supplies this pin. If the Z8 Encore! XP
F64XX Series is the SPI master, this pin is an output. If the Z8 Encore! XP
F64XX Series is the SPI slave, this pin is an input. It is multiplexed with a
general-purpose I/O 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
general-purpose I/O 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
general-purpose I/O pin.
Transmit Data. These signals are the transmit outputs from the UARTs. The
TXD signals are multiplexed with general-purpose I/O pins.
Receive Data. These signals are the receiver inputs for the UARTs and
IrDAs. The RXD signals are multiplexed with general-purpose I/O pins.
Clear To Send. These signals are control inputs for the UARTs. The CTS
signals are multiplexed with general-purpose I/O pins.
Driver Enable. 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 may be used to ensure an
external RS-485 driver is enabled when data is transmitted by the UART.
Timer Output 0-3. These signals are output pins from the timers. The Timer
Output signals are multiplexed with general-purpose I/O pins. T3OUT is not
available in 44-pin package devices.
Timer Input 0-3. These signals are used as the capture, gating and counter
inputs. The Timer Input signals are multiplexed with general-purpose I/O
pins. T3IN is not available in 44-pin package devices.
Analog Input. These signals are inputs to the ADC. The ADC analog inputs
are multiplexed with general-purpose I/O pins.
Analog-to-Digital converter reference voltage input. The VREF pin must be
left unconnected (or capacitively coupled to analog ground) if the internal
voltage reference is selected as the ADC reference voltage.
