DESCRIPTION
I UART channel 1 Data Set Ready or general purpose input (active LOW). If
unused, a pull-up or pull-down resistor is recommended on this pin.
I UART channel 1 Carrier Detect or general purpose input (active LOW). If
unused, a pull-up or pull-down resistor is recommended on this pin.
I UART channel 1 Ring Indicator or general purpose input (active LOW). If
unused, a pull-up or pull-down resistor is recommended on this pin.
I/O Multi-purpose input/output 0. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 1. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 2. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 3. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 4. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 5. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 6. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 7. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
I/O Multi-purpose input/output 8. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT
I/O Multi-purpose input/output 9. This pin defaults to an input with interrupts dis-
abled and is controlled using the MPIOSEL, MPIOLVL, MPIOINV, MPIO3T,
MPIOOD and MPIOINT configuration registers. If unused, a pull-up or pull-
down resistor is recommended on this pin.
