2 Module Interface

2.1 Electrical Interface

The Simblee Time-of-Flight (TOF) Module interface is a standard 7-big address I

C slave (slave ID 0x4C) device

capable up to 1Mbit/s.

The ToF module I

C interface supports a direct 8-bit addressing scheme used to access the module user’s register

set. This addressing scheme is functional also during standby mode since the module interface and the user’s

The module I

C interface supports an additional 16-bit indirect addressing scheme that is mainly used for

debugging purpose or special operations.

Both direct and indirect addressing schemes support the I

C address auto increment feature and word mode.

When the address auto increment feature is disabled, the word mode setting is ignored. Word mode setting

controls the data source/destination only when address auto increment is enabled. In such case the word mode

forces the transferred data stream to be sequentially read from (or written to) the same 15-byte location pointed

by the initial address.

The auto increment features and other modes of operation of the I

C interface are controlled by the I

C Init

Configuration Register.

2.1.1 I

C Single Byte Access

When accessing the device one byte at a time there is no dependency from the I

C Init Configuration Register.
