Data are transmitted in byte format (DATA). Each data transfer contains 8 bits. The number of bytes transferred

per transfer is unlimited. Data is transferred with the most significant bit (MSb) first. If a slave receiver does not

acknowledge the slave address (i.e. it is not able to receive because it is performing some real-time function) the

data line must be kept HIGH by the slave. The master can then abort the transfer. A LOW-to-HIGH transition on

the SDA line while the SCL line is HIGH is defined as a STOP condition. Each data transfer must be terminated

by the generation of a STOP (SP) condition.

In the presented communication format MAK is master acknowledge and NMAK is no master acknowledge.
