C Write Operation
After the START condition, in a single continuous transaction:
• The I²C Master sends the 7-bit slave address and 0 into the R/W bit (the byte sent
would be 0xA4 or 0xA6 dependent on the power-up value of MISO/ADDR).
• The I²C Master then sends the address of the first register to write.
• The I²C Master then sends 1-n data bytes which are written into sequential registers
(if valid) until the transaction is concluded with a STOP condition.
