Description

CFIFO Port Select Register

Fields

CURPIPE

CFIFO Port Access Pipe Specification

0 (0000): DCP(Defaultcontrolpipe)

0 (others): Setting prohibited

1 (0001): Pipe1

2 (0010): Pipe2

3 (0011): Pipe3

4 (0100): Pipe4

5 (0101): Pipe5

6 (0110): Pipe6

7 (0111): Pipe7

8 (1000): Pipe8

9 (1001): Pipe9

Reserved

This bit is read as 0. The write value should be 0.

ISEL

CFIFO Port Access Direction When DCP is Selected

0 (0): Reading from the buffer memory is selected

1 (1): Writing to the buffer memory is selected

Reserved

These bits are read as 00. The write value should be 00.

BIGEND

CFIFO Port Endian Control

0 (0): Little endian

1 (1): Big endian

Reserved

This bit is read as 0. The write value should be 0.

MBW

CFIFO Port Access Bit Width

0 (0): 8-bit width

1 (1): 16-bit width

Reserved

These bits are read as 000. The write value should be 000.

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 CFIFO.(In double buffer mode, the DTLN[8:0] 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 CFIFO.
