DS40001586D-page 111 PIC16(L)F1507 REGISTER 12-4: IOCBP: INTERRUPT-ON-CHANGE PORTB POSITIVE EDGE REGISTER R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 U-0 U-0 U-0 U-0 IOCBP7 IOCBP6 IOCBP5 IOCBP4 — — — — bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared bit 7-4 IOCBP<7:4>: Interrupt-on-Change PORTB Positive Edge Enable bits 1 = Interrupt-on-Change enabled on the pin for a positive going edge. IOCBFx bit and IOCIF flag will be set upon detecting an edge. 0 = Interrupt-on-Change disabled for the associated pin. bit 3-0 Unimplemented: Read as ‘0’ REGISTER 12-5: IOCBN: INTERRUPT-ON-CHANGE PORTB NEGATIVE EDGE REGISTER R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 U-0 U-0 U-0 U-0 IOCBN7 IOCBN6 IOCBN5 IOCBN4 — — — — bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared bit 7-4 IOCBN<7:4>: Interrupt-on-Change PORTB Negative Edge Enable bits 1 = Interrupt-on-Change enabled on the pin for a negative going edge. IOCBFx bit and IOCIF flag will be set upon detecting an edge. 0 = Interrupt-on-Change disabled for the associated pin. bit 3-0 Unimplemented: Read as ‘0’ REGISTER 12-6: IOCBF: INTERRUPT-ON-CHANGE PORTB FLAG REGISTER R/W/HS-0/0 R/W/HS-0/0 R/W/HS-0/0 R/W/HS-0/0 U-0 U-0 U-0 U-0 IOCBF7 IOCBF6 IOCBF5 IOCBF4 — — — — bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared HS - Bit is set in hardware bit 7-4 IOCBF<7:4>: Interrupt-on-Change PORTB Flag bits 1 = An enabled change was detected on the associated pin. Set when IOCBPx = 1 and a rising edge was detected on RBx, or when IOCBNx = 1 and a falling edge was detected on RBx. 0 = No change was detected, or the user cleared the detected change. bit 3-0 Unimplemented: Read as ‘0’ |
