Name:
Addresses: 0xFFF80014 (0), 0xFFF84014 (1)
Access Type: Write-only
This register is write-protected while CMDRDY is 0 in MCI_SR. If an Interrupt command is sent, this register is only writable
by an interrupt response (field SPCMD). This means that the current command execution cannot be interrupted or
modified.
• CMDNB: Command Number
MultiMedia Card bus command numbers are defined in the MultiMedia Card specification.
• RSPTYP: Response Type
• SPCMD: Special Command
