0 (Others): Setting prohibited

0 (0x0): Default Control Pipe

1 (0x1): Pipe 1

2 (0x2): Pipe 2

3 (0x3): Pipe 3

ISEL

CFIFO Port Access Direction When DCP Is Selected

0 (0): Select reading from the FIFO buffer

1 (1): Select writing to the FIFO buffer

BIGEND

CFIFO Port Endian Control

0 (0): Little endian

1 (1): Big endian

MBW

CFIFO Port Access Bit Width

0 (0): 8-bit width

1 (1): 16-bit width

REW

Buffer Pointer Rewind

0 (0): Do not rewind buffer pointer

1 (1): Rewind buffer pointer

RCNT

Read Count Mode

0 (0): The DTLN[8:0] bits (CFIFOCTR.DTLN[8:0], D0FIFOCTR.DTLN[8:0], D1FIFOCTR.DTLN[8:0]) are cleared when all receive data is read from the CFIFO. In double buffer mode, the DTLN[8:0] value is cleared when all data is read from only a single plane.

1 (1): The DTLN[8:0] bits are decremented each time the receive data is read from the CFIFO.
