bit 7 bit 0
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 7 bit 0
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 7-5 Unimplemented: Read as ‘0’
bit 4 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
bit 3 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
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.
