All reset events set the device in Mode OPM0. In a soft reset, the logic works further, but the registers use the
default values.
In case of a reset condition on the primary side, the behavior of the pin of the device is defined in Table 2-14.

2.4.10 Operation in Configuration Mode
This section describes the mechanisms to configure the device.
2.4.10.1 Static Configuration Parameters
Static parameters can configured when the device is in Mode OPM2 by writing the appropriate register.
Once Mode OPM2 is left with the SPI Command EXIT_CMODE, the configuration parameters are frozen on both
primary and secondary chips. This means in particular that write accesses to the corresponding registers are
invalidated. This prevents static configurations to be modified during runtime. Besides, the configuration
