DESCRIPTION
I/O Expansion Interface Data 7 (MSB). The trace capacitance between the mas-
ter and slave device must be less than 25pF.
I/O Expansion Interface Data 6. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 5. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 4. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 3. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 2. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 1. The trace capacitance between the master and
slave device must be less than 25pF.
I/O Expansion Interface Data 0 (LSB). The trace capacitance between the master
and slave device must be less than 25pF.
I/O Expansion Interface Read/Write Select. This is the the read/write select input
in the slave mode. This is the read/write select output in the master mode.
This pin can be left unconnected if there is no slave device. The trace capaci-
tance between the master and slave device must be less than 25pF.
I/O Expansion Interface Interrupt. This is the expansion interface interrupt output
in the slave mode. This is the expansion interface interrupt input in the mas-
ter mode. This pin can be left unconnected if there is no slave device. The
trace capacitance between the master and slave device must be less than
25pF.
I Slave Present. In master mode, connect this pin to VCC if there is a slave
device present. Connect this pin to GND to disable access to the slave
device (slave device may or may not be present). In slave mode, this pin
should be connected to GND.
I/O Multi-purpose input/output 0. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT
I/O Multi-purpose input/output 1. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 2. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 3. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 4. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 5. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
