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