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.

Note:
1. If the command is SEND_OP_COND, the CRC error flag is always present (refer to R3
response in the High Speed MultiMedia Card specification).
