Field Description
5:0
PTCSE[5:0]
Output Slew Rate Control Enable for Port C Bits — Each of these control bits determine whether output slew
rate control is enabled for the associated PTC pin. For port C pins that are configured as inputs, these bits have
no effect.
0 Output slew rate control disabled for port C bit n.
1 Output slew rate control enabled for port C bit n.
