Bits[7:6], CDATA Pad Pull-Up/Pull-Down
These bits enable or disable a weak pull-up or pull-down device
on the pad. The effective resistance of the pull-up or pull-down
is nominally 240 kΩ.
Bits[5:4], CLATCH Pad Pull-Up/Pull-Down
These bits enable or disable a weak pull-up or pull-down device
on the pad. The effective resistance of the pull-up or pull-down
is nominally 240 kΩ.
