IFR and IMR Registers Table 14. IFR and IMR Register Bit Fields BIT FUNCTION NUMBER NAME FUNCTION 15–14 – Reserved for future expansion 13 DMAC5 DMA channel 5 interrupt flag/mask bit 12 DMAC4 DMA channel 4 interrupt flag/mask bit 11 BXINT1/DMAC3 This bit can be configured as either the McBSP1 transmit interrupt flag/mask bit, or the DMA channel 3 interrupt flag/mask bit. The selection is made in the DMPREC register. 10 BRINT1/DMAC2 This bit can be configured as either the McBSP1 receive interrupt flag/mask bit, or the DMA channel 2 interrupt flag/mask bit. The selection is made in the DMPREC register. 9 HPINT Host to ’54x interrupt flag/mask 8 INT3 External interrupt 3 flag/mask 7 TINT1/DMAC1 This bit can be configured as either the timer1 interrupt flag/mask bit, or the DMA channel 1 interrupt flag/mask bit. The selection is made in the DMPREC register. 6 DMAC0 This bit can be configured as either reserved, or the DMA channel 0 interrupt flag/mask bit. The selection is made in the DMPREC register. 5 BXINT0 McBSP0 transmit interrupt flag/mask bit 4 BRINT0 McBSP0 receive interrupt flag/mask bit 3 TINT0 Timer 0 interrupt flag/mask bit 2 INT2 External interrupt 2 flag/mask bit 1 INT1 External interrupt 1 flag/mask bit 0 INT0 External interrupt 0 flag/mask bit |
