use ROMEO2 in a standalone configuration without any external control.
As long as a low level is applied on RESETB, the circuit stays in state 1. This configuration mode enables to write
or read the internal registers through the SPI interface.
After POR, the circuit is in state 0 and configuration registers’ content is set to the reset value. This enables to
