Command Token Format
Response Token Format
As shown in Figure 16-6, commands have a fixed code length of 48 Bits. Each command token
is preceded by a Start bit: a low level on MCMD line and succeeded by an End bit: a high level
on MCMD line. The command content is preceded by a Transmission bit: a high level on MCMD
line for a command token (host to card) and succeeded by a 7-bit CRC so that transmission
errors can be detected and the operation may be repeated.
Command content contains the command index and address information or parameters.
Table 71. Command Token Format
There are five types of response tokens (R1 to R5). As shown in Figure 16-7, responses have a
code length of 48 Bits or 136 Bits. A response token is preceded by a Start bit: a low level on
MCMD line and succeeded by an End bit: a high level on MCMD line. The command content is
preceded by a Transmission bit: a low level on MCMD line for a response token (card to host)
and succeeded (R1,R2,R4,R5) or not (R3) by a 7-bit CRC.
Response content contains mirrored command and status information (R1 response), CID regis-
ter or CSD register (R2 response), OCR register (R3 response), or RCA register (R4 and R5
response).
