24.3.14 Response Registers 0 to 16, D (RSPR0 to RSPR16, RSPRD)
RSPR0 to RSPR16 are command response registers, which are seventeen 8-bit registers. RSPRD
is an 8-bit CRC status register.
The number of command response bytes differs according to the command. The number of
command response bytes can be specified by RSPTYR in the MMCIF. The command response is
shifted-in from bit 0 in RSPR16, and shifted to the number of command response bytes × 8 bits.
Table 24.6 summarizes the correspondence between the number of command response bytes and
valid RSPR register.
Table 24.6 Correspondence between Command Response Byte Number and RSPR
RSPR0 to RSPR16 are simple shift registers. A command response that has been shifted in is not
automatically cleared, and it is continuously shifted until it is shifted out from bit 7 in RSPR0. To
clear unnecessary bytes to H'00, write an arbitrary value to each RSPR.
