Description
SDP0 Data Value
Used to read (write) a value of the software-controlled I/O pin SDP0. If SDP0
is configured as an output (SDP0_IODIR = 1b), this bit controls the value
driven on the pin. If SDP0 is configured as an input, all reads return the
current value of the pin.
SDP1 Data Value
Used to read (write) a value of the software-controlled I/O pin SDP1. If SDP1
is configured as an output (SDP1_IODIR = 1b), this bit controls the value
driven on the pin. If SDP1 is configured as an input, all reads return the
current value of the pin.
SDP2 Data Value
Used to read (write) a value of software-controlled I/O pin SDP2. If SDP2 is
configured as an output (SDP2_IODIR = 1b), this bit controls the value driven
on the pin. If SDP2 is configured as an input, all reads return the current value
of the pin.
SDP3 Data Value
Used to read (write) a value of the software-controlled I/O pin SDP3. If SDP3
is configured as an output (SDP3_IODIR = 1b), this bit controls the value
driven on the pin. If SDP3 is configured as an input, all reads return the
current value of the pin.

0b
SDP4 Data Value
Used to read (write) a value of the software-controlled I/O pin SDP4. If SDP4
is configured as an output (SDP4_IODIR = 1b), this bit controls the value
driven on the pin. If SDP4 is configured as an input, all reads return the
current value of the pin.
5
0b
SDP5 Data Value
Used to read (write) a value of the software-controlled I/O pin SDP5. If SDP5
is configured as an output (SDP5_IODIR = 1b), this bit controls the value
driven on the pin. If SDP5 is configured as an input, all reads return the
current value of the pin.

SDP0 Pin Directionality
Controls whether or not software-controlled pin SDP0 is configured as an input
or output (0b = input, 1b = output). This bit is not affected by software or
system reset, only by initial power-on or direct software writes.
SDP1 Pin Directionality
Controls whether or not software-controlled pin SDP1 is configured as an input
or output (0b = input, 1b = output). This bit is not affected by software or
system reset, only by initial power-on or direct software writes.
SDP2 Pin Directionality
Controls whether or not software-controlled pin SDP2 is configured as an input
or output (0b = input, 1b = output). This bit is not affected by software or
system reset, only by initial power-on or direct software writes.
