31.3.7
RSPR0 to RSPR16 are seventeen 8-bit command response registers. RSPRD is a 5-bit data
register.
The number of command response bytes differs according to the command. The number of
command response bytes can be specified by the response type register (RSPTYR) in the MMCIF.
The command response is shifted-in from the bit 0 in RSPR16, and shifted to the number of
command response bytes × 8 bits. Table 31.4 summarizes the correspondence between the number
of command response bytes and valid RSPR.
