Operating Modes
The different modes of operation and EEPROM information are presented in the following sections.
Operational Mode Selection Flow
During the power up sequence, the AT2LP queries the I
shown here, and checks to see if ARESET# is configured for Board Manufacturing Test Mode.

Document Number: 001-05809 Rev. *H
If no EEPROM is detected, the AT2LP uses the values in the factory-programmable (fused) memory space. See
Data on page 20
If an EEPROM signature of 0x4D4D is found, the CY7C68300C/CY7C68301C uses the same pinout and EEPROM format as the
CY7C68300A (EZ-USB AT2+).
If an EEPROM signature of 0x534B is found, the AT2LP uses the values stored in the EEPROM to configure the USB descriptors
for normal operation.
If an EEPROM is detected, but an invalid signature is read, the AT2LP defaults into Board Manufacturing Test Mode.
for more information. This is not a valid mode of operation if no factory programming has been done.
