Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
IOCB<7:4>: Interrupt-on-Change PORTB control bits
1
= Interrupt-on-change enabled
(1)
0
= Interrupt-on-change disabled
Note 1:
Interrupt-on-change requires that the RBIE bit (INTCON<3>) is set.

bit 4
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
bit 3
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
bit 2
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
bit 1
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
bit 0
SLRA: PORTA Slew Rate Control bit
1
= All outputs on PORTA slew at a limited rate
(2)
0
= All outputs on PORTA slew at the standard rate
Note 1:
These bits are available on PIC18(L)F4XK22 devices.
2:
The slew rate of RA6 defaults to standard rate when the pin is used as CLKOUT.
