Description

Specify various options for sending commands to the card and the expected response.

ARM_MCI_xxx flags are sent with the function ARM_MCI_SendCommand as the parameter flag. It controls the behavior of the command sent to the card and provides information about the expected response from the card.

The following codes are defined:
