Table 6-2. Example CfgCB
6.1.2
The mfg_load and mfg_read vendor-specific commands will
be passed down through the bulk pipe in the CBWCB portion
of the CBW. The format of this MFGCB is shown below. Byte
0 is a vendor-specific command designator whose value is
configurable and set in the configuration data. Byte 1 must be
Table 6-3. Example MfgCB
6.1.2.1 Mfg_load
During a mfg_load, the CY7C68300A goes into Manufacturing
Test Mode. Manufacturing Test Mode is provided as a means
to implement board or system level interconnect tests. During
Manufacturing Test Mode operation, all outputs not directly
associated with USB operation are controllable. Normal
control of the output pins are disabled. Control of the select

CBWCB (CfgCB or MfgCB)
dCBWDataTransferLength
0x27 to identify MfgCB. Byte 2–15 are reserved and must be
set to zero.
The data transfer length will be determined by the CBW Data
Transfer
(dCBWDataTransferLength) of the CBW. The type/direction of
the command is determined by the direction bit specified in
byte 12, bit 7 (bmCBWFlags) of the CBW.
CY7C68300A IO pins and their three-state controls are
mapped to the ATAPI data packet associated with this
request. (See the following table for explanation of the
required mfg_load data format.) This requires a write of seven
bytes. To exit Manufacturing Test Mode, a hard reset
(#RESET) is required.
