The I2C-bus protocol is shown in Fig.4. The sequence is initiated with a START
condition (S) from the I2C-bus master which is followed by one of the two BL55087 slave
addresses available. Two BL55087s with the corresponding SA0 level acknowledge in
parallel with the slave address but two BL55087s with the alternative SA0 level ignore the
whole I2C-bus transfer. After acknowledgement, one or more command bytes (m) follow
which define the status of the addressed BL55087s. The last command byte is tagged with a
cleared most significant bit, the continuation bit C. The command bytes are also
acknowledged by all addressed BL55087s on the bus. After the last command byte, a series of
display data bytes(n) may follow. These display bytes are stored in the display RAM at the
address specified by the data pointer and the subaddress counter. Both data pointer and
subaddress counter are automatically updated and the data is directed to the intended
BL55087 device. The acknowledgement after each byte is made only by the A0 addressed
BL55087. After the last display byte, the I2C-bus master issues a STOP condition (P).
Fig 4
4. command decoder
The command decoder identifies command bytes that arrive on the I2C-bus. All
available commands carry a continuation bit C in their most significant bit position. The five
commands available to the BL55077 are defined in Fig 5.
