Field Name
Bit (1)
If bits 1 and 2 are both 0, the number of logical units will be
determined by searching the ATA and CF buses for devices.
Bit (0)
Search for ATA devices when VBUS returns. If this bit is set,
the ATA bus will be searched for ATA devices every time
AT2LP is plugged into a computer.
Must be set to 0x00.

USB packet size supported for default pipe.
Vendor ID. Cypress’s Vendor ID may only be used for evalu-
ation purposes, and not in released products.
Product ID.
Device release number in BCD LSB (product release
number).
Device release number in BCD MSB (silicon release
number).
Index to manufacturer string. This entry must equal half of
the address value where the string starts or 0x00 if the string
does not exist.
Index to product string. This entry must equal half of the
address value where the string starts or 0x00 if the string
does not exist.
Index to serial number string. This entry must equal half of
the address value where the string starts or 0x00 if the string
does not exist. The USB Mass Storage Class Bulk-Only
Transport Specification requires a unique serial number (in
upper case, hexadecimal characters) for each device.
Number of configurations supported.
1 for mass storage: 2 for HID: 3 for CSM
