Slew Rate Control Enable for Port A Bits — For port A pins that are outputs, these read/write control bits
determine whether the slew rate controlled outputs are enabled. For port A pins that are configured as inputs,
these bits are ignored.
0 Slew rate control disabled.
1 Slew rate control enabled.
Data Direction for Port A Bits — These read/write bits control the direction of port A pins and what is read for
PTAD reads.
0 Input (output driver disabled) and reads return the pin value.
1 Output driver enabled for port A bit n and PTAD reads return the contents of PTADn.
