Table 76. R5 Response Format
There are two types of data packets: stream and block. As shown in Figure 16-8, stream data
packets have an indeterminate length while block packets have a fixed length depending on the
block length. Each data packet is preceded by a Start bit: a low level on MCMD line and suc-
ceeded by an End bit: a high level on MCMD line. Due to the fact that there is no predefined end
