13.2 State Machine
The configuration mode is selected by the microcontroller unit (MCU) to write to the internal registers (to
configure the system) or to read them. In this mode, the SPI is a slave. The analog parts (receiver) remain
in the state (on, off) they were in prior to entering configuration mode, until a new configuration changes
them. In configuration mode, data can not be received. As long as a low level is applied to CONFB, the
circuit stays in State 1, the only state in this mode.

configuration mode. SPI startup time corresponds to the addition of the crystal oscillator lock time
(parameter 5.10) and the PLL lock time (parameter 5.9).
