DEV3_ID_STR
This ID string is associated with the Secure Digital / MultiMediaCard device.
BYTE
NAME
DESCRIPTION
7:0
INQ_VEN_STR
If bit 4 of the 1st attribute byte is set, the device will use these strings in
response to a USB inquiry command, instead of the USB descriptor
manufacturer and product ID strings.

DESCRIPTION
4:0
INQ_PRD_STR
If bit 4 of the 1st attribute byte is set, the device will use these strings in
response to a USB inquiry command, instead of the USB descriptor
manufacturer and product ID strings.
BIT
NAME
DESCRIPTION
7:0
DYN_NUM_LUN
These bytes are used to specify the number of LUNs the device exposes to
the host. These bytes are also used for icon sharing by assigning more than
one LUN to a single icon. This is used in applications where the device
utilizes a combo socket and the OEM wishes to have only a single icon
displayed for one or more interfaces.
If this field is set to "FF", the program assumes that you are using the default
value and icons will be configured per the default configuration.
BYTE
NAME
DESCRIPTION
3:0
DEV_LUN_MAP
These registers map a device controller (SD/MMC, SM, and MS) to a Logical
Unit Number (LUN). The device reports the mapped LUNs to the USB host
in the USB descriptor during enumeration. The icon installer associates
custom icons with the LUNs specified in these fields.
Setting a register to "FF" indicates that the device is not mapped. Setting all
of the DEV_LUN_MAP registers for all devices to "FF" forces the use of the
default mapping configuration. Not all configurations are valid. Valid
configurations depend on the hardware, packaging, and OEM board layout.
The number of unique LUNs mapped must match the value in the Section
