8.1.2.1
Write: START - 34H - 00H - Data_for_00 - STOP
Write with auto-increment: START - 34H - 00H - data_for_00 - data_for_01 - data_for_02 - STOP
Auto-increment ‘wrap around’: START - 34H - 07H - data_for_07 - data_for_00 - data_for_01 - STOP
Write without auto-increment: START - 34H - F5H - data_for_05 - data_for_05 - data_for_05 - STOP
Read: START - 35H - data_from_ IC - STOP.
