U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
— — IOCA5 IOCA4 IOCA3 IOCA2 IOCA1 IOCA0
bit 7 bit 0
bit 7-6 Unimplemented: Read as ‘0’
bit 5-0 IOCA<5:0>: Interrupt-on-Change PORTA Control bit
1 = Interrupt-on-change enabled
0 = Interrupt-on-change disabled
Note: Global interrupt enable (GIE) must be enabled for individual interrupts to be
recognized.
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
