External Peripheral Interface (EPI)
Register 19: EPI Read FIFO (EPIREADFIFO), offset 0x070
Register 20: EPI Read FIFO Alias 1 (EPIREADFIFO1), offset 0x074
Register 21: EPI Read FIFO Alias 2 (EPIREADFIFO2), offset 0x078
Register 22: EPI Read FIFO Alias 3 (EPIREADFIFO3), offset 0x07C
Register 23: EPI Read FIFO Alias 4 (EPIREADFIFO4), offset 0x080
Register 24: EPI Read FIFO Alias 5 (EPIREADFIFO5), offset 0x084
Register 25: EPI Read FIFO Alias 6 (EPIREADFIFO6), offset 0x088
Register 26: EPI Read FIFO Alias 7 (EPIREADFIFO7), offset 0x08C
Important: This register is read-sensitive. See the register description for details.
This register returns the contents of the NBRFIFO or 0 if the NBRFIFO is empty. Each read returns
the data that is at the top of the NBRFIFO, and then empties that value from the NBRFIFO. The
alias registers can be used with the LDMIA instruction for more efficient operation (for up to 8
registers). See Cortex™-M3/M4 Instruction Set Technical User's Manual for more information on
the LDMIA instruction.
