Port H[3:0]. These pins are used for general-purpose I/O.
Serial Clock. This is the output clock for the I
general-purpose I/O pin. When the general-purpose I/O 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
This pin is multiplexed with a general-purpose I/O pin. When the
general-purpose I/O pin is configured for alternate 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
F64XX Series is the SPI master, this pin may be configured as the Slave
Select output. If the Z8 Encore! XP F64XX Series is the SPI slave, this pin is
the input slave select. It is multiplexed with a general-purpose I/O pin.
Port A[7:0]. These pins are used for general-purpose I/O and support
