DESCRIPTION
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 must be left unconnected if there is no slave device.
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 must be left unconnected if there is no slave device.
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.

figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT
I/O Multi-purpose input/output 9. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 10. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 11. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 12. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
I/O Multi-purpose input/output 13. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
