6. To continue transmitting, write the next transmit data in ICDR. Transmission of the next byte
will begin in synchronization with the internal clock.
Steps 4 to 6 can be repeated to transmit data continuously. To end the transmission, write 0 in
BBSY and 0 in SCP in ICSR. This generates a stop condition by causing a low-to-high transition
of SDA while SCL is high.
