Functional Description
4.6.3
Two-wire Interface Mode (SIC2)
In this mode a two-wire serial interface is used to program the device's internal registers, configuring the operation
of the M08035/M08045. When in SIC2 mode, MF[0:5] pins are configured as shown below.

Each device has an individual address and is addressed using an address byte, which is latched upon Power-On-
Reset (POR). In this mode, the M08035/M08045 are I²C-compatible slave devices that can operate at 100 kHz and
400 kHz for all allowed voltages seen at the DV_DDIO pin.
The M08035/M08045 allow for forty different addresses to be programmed using the inputs ADD[3:0]; these inputs
have three states, low (L), high (H) and floating (F). The slave addresses are from 21h to 48h.
