Description

SD Card Interrupt Flag Register 2

Fields

CMDE

Command Error

0 (0): Command error not detected

1 (1): Command error detected

CRCE

CRC Error

0 (0): CRC error not detected

1 (1): CRC error detected

ENDE

END Error

0 (0): End bit error not detected

1 (1): End bit error detected

DTO

Data Timeout

0 (0): Data timeout not detected

1 (1): Data timeout detected

ILW

SD_BUF Illegal Write Access

0 (0): Illegal write access to the SD_BUF register not detected

1 (1): Illegal write access to the SD_BUF register detected

ILR

SD_BUF Illegal Read Access

0 (0): Illegal read access to the SD_BUF register not detected

1 (1): Illegal read access to the SD_BUF register detected

RSPTO

Response Timeout

0 (0): Response timeout not detected

1 (1): Response timeout detected

SDD0MON

SDDAT0Indicates the SDDAT0 state of the port specified by SD_PORTSEL.

0 (0): SDDAT0 is set to 0.

1 (1): SDDAT0 is set to 1.

BRE

SD_BUF Read Enable

0 (0): Data cannot be read from SD_BUF0.

1 (1): Data can be read from SD_BUF0.

BWE

SD_BUF Write Enable

0 (0): Data cannot be written in SD_BUF0.

1 (1): Data can be written in SD_BUF0.

SD_CLK_CTRLEN

When a command sequence is started by writing to SD_CMD, the CBSY bit is set to 1 and, at the same time, the SCLKDIVEN bit is set to 0. The SCLKDIVEN bit is set to 1 after 8 cycles of SDCLK have elapsed after setting of the CBSY bit to 0 due to completion of the command sequence.

0 (0): The SD/MMC bus (CMD, DAT) is busy. Writing to the SCLKEN and DIV bits in SD_CLK_CTRL is not possible.

1 (1): The SD/MMC bus (CMD, DAT) is not busy.

CBSY

Command Type Register Busy

0 (0): A command sequence is being executed.

1 (1): A command sequence has been completed.

ILA

Illegal Access Error

0 (0): Illegal access error not detected

1 (1): Illegal access error detected
