RESET

Software Reset Register

Description

The built-in Automatic Standard Recognition System (Autostandard) can be disabled. In this case,

the Software Reset function (bits SOFT_LRST1 and SOFT_LRST2) can be used to implement the

Automatic Standard Recognition by I²C Software. This is not required if the built-in Automatic

Standard Recognition System function is used (default).
