SOFT_LRST1 SOFT_LRST2 SOFT_RST
Description
The built-in Automatic Standard Recognition System (AUTOSTD) can be disabled by bit
AUTO_OFF (when high). In this case, the Software Reset function (bits SOFT_LRESTART1 and
SOFT_LRESTART2) 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).
