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

SLRE: PORTE Slew Rate Control bit⁽¹⁾
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⁾
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⁽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.
