Description

D1FIFO Port Select Register

Fields

CURPIPE

FIFO Port Access Pipe Specification

0 (0000): DCP (Default control pipe)

0 (others): Setting prohibited

1 (0001): Pipe 1

2 (0010): Pipe 2

3 (0011): Pipe 3

4 (0100): Pipe 4

5 (0101): Pipe 5

6 (0110): Pipe 6

7 (0111): Pipe 7

8 (1000): Pipe 8

9 (1001): Pipe 9

BIGEND

FIFO Port Endian Control

0 (0): Little endian

1 (1): Big endian

MBW

FIFO Port Access Bit Width

0 (0): 8-bit width

1 (1): 16-bit width

DREQE

DMA/DTC Transfer Request Enable

0 (0): DMA/DTC transfer request is disabled.

1 (1): DMA/DTC transfer request is enabled.

DCLRM

Auto Buffer Memory Clear Mode Accessed after Specified Pipe Data is Read

0 (0): Auto buffer clear mode is disabled.

1 (1): Auto buffer clear mode is enabled.

REW

Buffer Pointer Rewind

0 (0): The buffer pointer is not rewound.

1 (1): The buffer pointer is rewound.

RCNT

Read Count Mode

0 (0): The DTLN[8:0] bits (CFIFOCRT.DTLN[8:0], D0FIFOCRT.DTLN[8:0], D1FIFOCRT.DTLN[8:0]) are cleared when all of the receive data has been read from the DnFIFO.(In double buffer mode, the DTLN bit Value is cleared when all the data has been read from only a single plane.)

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