4.26. EEPROM Interface
The Si2494/39 supports an optional serial peripheral interface (SPI) bus serial EEPROM Mode 3 with a 16-bit (8–
64 kbit range) address. The EEPROM is intended first for setting custom defaults, second for automatically loading
firmware upgrades, and third to allow for user-defined AT command macros for use in custom AT commands or
country codes. See AN93 for complete details.
4.27. AT Commands
At powerup, the Si2494/39 is in the AT command mode. In command mode, the modem monitors the input (serial
or parallel) checking constantly for a valid command (AT commands are described in Table 10.)
