Multipurpose I/O Bank 3 Latch
These read/write register bits store the power-on value of
the I/O pins MPIO3_0, MPIO3_1, MPIO3_2, and
MPIO3_3. The values on these pins are latched into this
register on the deasserting edge of the RESET/ input
signal or the internal power-on reset.
Reserved
These read/write register bits determine if pull-downs are
active on the I/O pins MPIO3_0, MPIO3_1, MPIO3_2,
and MPIO3_3. A value of 1 indicates the pull-down is
active, a value of 0 indicates the pull-down is inactive.
