As shown in Figure 16-13, the command line controller is divided in 2 channels: the command
transmitter channel that handles the command transmission to the card through the MCMD line
and the command receiver channel that handles the response reception from the card through
the MCMD line. These channels are detailed in the following sections.
For sending a command to the card, user must load the command index (1 Byte) and argument
(4 Bytes) in the command transmit FIFO using the MMCMD register. Before starting transmis-
sion by setting and clearing the CMDEN bit in MMCON1 register, user must first configure:
•
•
17 - Byte FIFO
5-Byte FIFO
MMCMD
MMCMD
RESPEN bit in MMCON1 register to indicate whether a response is expected or not.
RFMT bit in MMCON0 register to indicate the response size expected.
