Name:
Address:
Access:
This register is write-protected while CMDRDY is 0 in HSMCI_SR. If an Interrupt command is sent, this register is only
writeable by an interrupt response (field SPCMD). This means that the current command execution cannot be interrupted
or modified.
• CMDNB: Command Number
This is the command index.
• RSPTYP: Response Type
• SPCMD: Special Command
