Power-on reset
The circuit is provided with a power-on reset function.
When the power supply is switched on an internal pulse will be generated that will reset the internal memory S₀, in the
initial state all the switches will be in the off position and the OFF input is active (D₇ - D₀ = 0) (I²C mode), position defined
via SDA and SCL inputs (non-I²C mode).
When the power supply decreases below 5 V a pulse will be generated and the internal memory will be reset. The
behaviour of the switches will be the same as described above.
