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. An EEPROM
boundary exists between addresses 0x7F and 0x80. No single
EEPROM write command shall write to addresses on both sides of that
EEPROM boundary.
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.
