PTASEn]
Output Slew Rate Control Enable for Port A Bits — Each of these control bits determine whether output slew
rate control is enabled for the associated PTA pin. For port A pins that are configured as inputs, these bits have
no effect.
0 Output slew rate control disabled for port A bit n.
1 Output slew rate control enabled for port A bit n.
