//*(pchRespBuff ) = (BYTE)(START_BIT | TRANSMISSION_BIT |
// START_RESERVED); <- why it is blocked?
above code in CSDIOControllerBase::GetCommandResponse function is
blocked,
but I couldn't figure out what the reason is.
Please, let me know.
Thanx in advance.
Have a good day~
SD_API_STATUS CSDIOControllerBase::GetCommandResponse(PSD_BUS_REQUEST
pRequest)
{
..... abbreviated....
case ResponseR2:
//DEBUGMSG(1, (TEXT("R2=0x%x\r\n"), vm_pXSDReg-
XSD_RSP_0));//--- LONG RESPONSE (136 bits total ; 17 bytes)---
// Format: { START_BIT(1) | TRANSMISSION_BIT(1) |
RESERVED(6) | CARD_STATUS(127) | END_BIT(1) }
//
// NOTE: In this implementation, the caller doesn't
require the upper 8 bits of reserved data.
// Consequently, these bits aren't included and the
response info is copied directly into
// the beginning of the supplied buffer.
//
//*(pchRespBuff ) = (BYTE)(START_BIT | TRANSMISSION_BIT
|
// START_RESERVED); <- why it is blocked?
