122 / 496 page  PIC18F6585/8585/6680/8680 DS30491C-page 120 2004 Microchip Technology Inc. 9.4 IPR Registers The IPR registers contain the individual priority bits for the peripheral interrupts. Due to the number of peripheral interrupt sources, there are three Peripheral Interrupt Priority registers (IPR1, IPR2 and IPR3). The operation of the priority bits requires that the Interrupt Priority Enable (IPEN) bit be set. REGISTER 9-10: IPR1: PERIPHERAL INTERRUPT PRIORITY REGISTER 1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 PSPIP(1) ADIP RCIP TXIP SSPIP CCP1IP TMR2IP TMR1IP bit 7 bit 0 bit 7 PSPIP: Parallel Slave Port Read/Write Interrupt Priority bit(1) 1 = High priority 0 = Low priority Note 1: Available in Microcontroller mode only. bit 6 ADIP: A/D Converter Interrupt Priority bit 1 = High priority 0 = Low priority bit 5 RCIP: USART Receive Interrupt Priority bit 1 = High priority 0 = Low priority bit 4 TXIP: USART Transmit Interrupt Priority bit 1 = High priority 0 = Low priority bit 3 SSPIP: Master Synchronous Serial Port Interrupt Priority bit 1 = High priority 0 = Low priority bit 2 CCP1IP: CCP1 Interrupt Priority bit 1 = High priority 0 = Low priority bit 1 TMR2IP: TMR2 to PR2 Match Interrupt Priority bit 1 = High priority 0 = Low priority bit 0 TMR1IP: TMR1 Overflow Interrupt Priority bit 1 = High priority 0 = Low priority 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 |
