Description
Port A: These pins are used for general-purpose I/O.
Port B: These pins are used for GPIO.
Port C: These pins are used for GPIO.
Port D: These pins are used for GPIO. PD0 is output only.
Port E: These pins are used for GPIO.
UART0/1 and IrDA0/1.
Receive Data 0-1: These signals are the receive input for the 
UART0/1 and IrDA0/1.
Clear To Send 0-1: These signals are the flow control input for the UART0/1.
Driver Enable 0-1: These signals allow automatic control of external 
RS-485 drivers. These signals are approximately the inverse of the TXE
(Transmit Empty) bit in the UART Status 0/1 register. The DE0/1 signal can
be used to ensure the external RS-485 driver is enabled when data is
transmitted by the UART0/1.
I
F1680 Series is the I
pin is an input. When the GPIO pin is configured for alternate function to
enable the SCL function, this pin is open-drain.
Serial Data: This open-drain pin transfers data between the I
external I
function to enable the SDA function, this pin is open-drain.
Slave Select: This signal can be an output or an input. If the Z8 Encore! XP
F1680 Series is the SPI master, this pin may be configured as the Slave
Select output, and if it is the SPI slave, this pin is the input slave select.
SPI Serial Clock: The SPI master supplies this signal. If the Z8 Encore! XP
F1680 Series is the SPI master, this pin is output and if it is the SPI slave, this
pin is an input.
Master Out Slave In: This signal is the data output from the SPI master
device and the data input to the SPI slave device.
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 0-1: These signals are the transmit output from the 
