Description
6:0
PTDPE[6:0]
Pullup Enable for Port D Bits — For port D pins that are inputs, these read/write control bits determine whether
internal pullup devices are enabled. For port D pins that are configured as outputs, these bits are ignored and
the internal pullup devices are disabled.
0 Internal pullup device disabled.
1 Internal pullup device enabled.

Field
Description
6:0
Data Direction for Port D Bits — These read/write bits control the direction of port D pins and what is read for
PTDDD[6:0] PTDD reads.
0 Input (output driver disabled) and reads return the pin value.
1 Output driver enabled for port D bit n and PTDD reads return the contents of PTDDn.
