Description
Response Type 5
Sets data busy status from the MMC card.
This bit is set to perform CRC check for the response
(R2 response of MMC mode) when the command that
reads, as a response, the register value of the
multimedia card, including CRC7, is executed.
RTY2 to RTY0 must be set to 101.
Response Type 5
Sets data busy status from the MMC card.
0: A command without data busy
1: A command with data busy
Response Type 4
Specifies that the command response CRC is checked
through CRC7. Bits RTY2 to RTY0 should be set to
100.
0: Does not check CRC through CRC7
1: Checks CRC through CRC7
Reserved
These bits are always read as 0. The write value should
always be 0.
Response Types 2 to 0
These bits specify the number of command response
bytes.
000: A command needs no command response.
001: Setting prohibited
010: Setting prohibited
011: Setting prohibited
100: A command needs 6-byte command responses.
101: A command needs a 17-byte command response.
110: Setting prohibited
111: Setting prohibited
Specified by R1, R1b, R3, R4, and R5 responses.
Specified by R2 response.
