AC4490 User’s Manual
EE PROM Byte Re ad
Upon receiving this command, a transceiver will respond with the
desired data from the addresses requested by the OEM Host.
EE PROM Byte W ri t e
Upon receiving this command, a transceiver will write the data byte to
the specified address but will not echo it back to the OEM Host until the
EEPROM write cycle is complete (up to 10 ms).
Multiple byte writes of up to 128 bytes are allowed.
boundary exists between addresses 0x7F and 0x80.
EEPROM write command shall write to addresses on both sides of that
EEPROM boundary.
Note: Only the last byte wriiten will be displayed in the command
response.
R es et
The OEM Host issues this command to perform a soft reset of the
transceiver. Any transceiver settings modified by CC commands will
revert to the values stored in the EEPROM.
