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