PIC18F2XK20/4XK20
10.8
The output slew rate of each port is programmable to
select either the standard transition rate or a reduced
transition rate of 0.1 times the standard to minimize
EMI. The reduced transition time is the default slew
rate for all ports.

Port Slew Rate Control
These bits are not implemented on PIC18F2XK20 devices.
The slew rate of RA6 defaults to standard rate when the pin is used as CLKOUT.
Unimplemented: Read as ‘0’
SLRE: PORTE Slew Rate Control bit
1 = All outputs on PORTE slew at a limited rate
0 = All outputs on PORTE slew at the standard rate
SLRD: PORTD Slew Rate Control bit
1 = All outputs on PORTD slew at a limited rate
0 = All outputs on PORTD slew at the standard rate
SLRC: PORTC Slew Rate Control bit
1 = All outputs on PORTC slew at a limited rate
0 = All outputs on PORTC slew at the standard rate
SLRB: PORTB Slew Rate Control bit
1 = All outputs on PORTB slew at a limited rate
0 = All outputs on PORTB slew at the standard rate
SLRA: PORTA Slew Rate Control bit
1 = All outputs on PORTA slew at a limited rate
0 = All outputs on PORTA slew at the standard rate
