Pullup Enable for Port E Bits — For port E pins that are inputs, these read/write control bits determine whether
internal pullup devices are enabled. For port E 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.
Slew Rate Control Enable for Port E Bits — For port E pins that are outputs, these read/write control bits
0 Slew rate control disabled.
1 Slew rate control enabled.
Data Direction for Port E Bits — These read/write bits control the direction of port E pins and what is read for
0 Input (output driver disabled) and reads return the pin value.
1 Output driver enabled for port E bit n and PTED reads return the contents of PTEDn.
