Programming the EEPROM
There are three methods of programming the EEPROM:
■
■
■
Any vendor-specific USB write request to the serial ROM device
configuration space simultaneously update internal configuration
register values as well. If the I
vendor specific USB commands, the AT2LP must be
synchronously reset (toggle RESET#) before configuration data
is reloaded.
The AT2LP supports a subset of the ’slow mode’ specification
(100 kHz) required for 24LCXXB EEPROM family device
support.
Synchronization’ (the SCL pin is output only), ’10-bit addressing’,
and ’CBUS device support’ are not supported. Vendor-specific
USB commands enable the AT2LP to address up to 256 bytes
of EEPROM data.
Table 12. EEPROM-related Vendor-Specific Commands
READ_CONFIG_DATA
This USB request enables data retrieval from the data source specified by the wValue field. Data is retrieved beginning at the address
specified by the wIndex field (see
Legal values for wValue are as follows:
■
■
Illegal values for wValue result in an undefined operation. Attempted reads from an I
in an undefined operation. Attempts to read configuration bytes with starting addresses greater than 0xF also, result in an undefined
operation.
