SOFTWARE SPECIFICATION FOR BOTH MODES
Auto increment
If bit I in the subaddress byte is set to ”1”, the autoincrement of the subaddress is enabled.
Reset condition
A Power-On-Reset is invoked if the Supply-Voltage V dd is below than 3.5V. After POR the following
data is written automatically into the registers of all subaddresses :
