Table 34-7.
The HSMCI_ARGR contains the argument field of the command.
To send a command, the user must perform the following steps:
The command is sent immediately after writing the command register.
While the card maintains a busy indication (at the end of a STOP_TRANSMISSION command
CMD12, for example), a new command shall not be sent. The NOTBUSY flag in the status regis-
ter (HSMCI_SR) is asserted when the card releases the busy indication.
If the command requires a response, it can be read in the HSMCI response register
(HSMCI_RSPR). The response size can be from 48 bits up to 136 bits depending on the com-
mand. The HSMCI embeds an error detection to prevent any corrupted data during the transfer.
The following flowchart shows how to send a command to the card and read the response if
needed. In this example, the status register bits are polled but setting the appropriate bits in the
interrupt enable register (HSMCI_IER) allows using an interrupt method.

TRCMD (transfer command)
TRDIR (transfer direction)
TRTYP (transfer type)
IOSPCMD (SDIO special command)
• Fill the argument register (HSMCI_ARGR) with the command argument.
• Set the command register (HSMCI_CMDR) (see
