Notes/Warnings
...
- This function will be called even if no response is expected from the command.
...
- This function will not be called if
FSDev_SD_Card_BSP_CmdStart()returned an error.
...
- The data stored in the response buffer should include only the response data, i.e., should not include the start bit, transmission bit, command index, CRC and end bit.
- For a command with a normal (48-bit) response, a 4-byte response should be stored in
p_resp. - For a command with a long (136-bit) response, a 16-byte response should be returned in
p_resp:The first 4-byte word should hold bits 127..96 of the response.
The second 4-byte word should hold bits 95..64 of the response.
The third 4-byte word should hold bits 63..32 of the response.
The four 4-byte word should hold bits 31.. 0 of the response.
- For a command with a normal (48-bit) response, a 4-byte response should be stored in
Example
The implementation of FSDev_SD_Card_BSP_CmdWaitEnd() in is targeted for the same host controller as the other listings in this chapter; for more information, see FSDev_SD_Card_BSP_CmdStart().
