Table 6-4. Mfg_load Data Format
6.1.2.2 Mfg_read
This USB request returns a “snapshot in time” of select
CY7C68300A input pins. The input pin states are bit-wise
mapped to the ATAPI data associated with this request.
CY7C68300A input pins not directly associated with USB
operation can be sampled at any time during Manufacturing
Test Mode operation. See the following table for an expla-
nation of the mfg_read data format. The data length shall
always be eight bytes.

6.2
In Normal Operation Mode, the chip behaves as a USB 2.0 to
ATA/ATAPI bridge. This includes all typical USB device states
(powered, configured, etc.). The USB descriptors are returned
according to the values stored in the external EEPROM. An
external EEPROM is required for Mass Storage Class Bulk-
Only Transport compliance, since a unique serial number is
required for each device. Also, Cypress requires customers to
use their own Vendor and Product IDs for final products.
