... Data Transfer All Bytes are sent MSB (Most Significant Bit) bit first and the write data transfer is closed by a STOP. The MCU can write data into the KA2504 registers. To write data into the KA2504, after a start, MCU must send : 2 - The I C address slave byte with a low level for R/W bit (bit 1) - The byte of the internal register address where the MCU wants to write data ...
