SDP3_IODIR
11
0b¹
SDP3 Pin Directionality
Controls whether or not software-controlled pin SDP3 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.
SDP4_IODIR
12
0b
SDP4 Pin Directionality
Controls whether or not software-controlled pin SDP4 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.
SDP5_IODIR
13
0b
SDP5 Pin Directionality
Controls whether or not software-controlled pin SDP5 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.
