Q_LDO1 had decreased below 3.3V (max.), the SPI will reset to the default settings
including the 8ms delay time. If the voltage on Q_LDO1 during sleep or power off mode
was kept above 3.3V the delay time set by the last SPI command is valid.

2.7
A RAM good flag will be set within the SPI status word when the Q_LDO1 voltage drops
below 2.3V. A second one will be set if Q_LDO2 drops below typical 1.4V. Both RAM
good flags can be read after power up to determine if a cold or warm start needs to be
processed. Both RAM good flags will be reset after each SPI cycle.
2.8
A hardware error pin indicates any fault conditions on the chip. It should be connected to
an interrupt input of the microcontroller. A low signal indicates an error condition. The
microcontroller can read the root cause of the error by reading the SPI register.
2.9
The on board window watchdog for supervision of the µC works in combination with the
SPI. The window watchdog logic is turned off per default and can be activated by one
special bit combination in the SPI command word. When operating, the window
watchdog is triggered when CS is low and Bit WD-Trig in the SPI command word is set
to “1”. The watchdog trigger is recognized with the low to high transition of the CS signal.
To allow reading the SPI at any time without getting a reset due to misinterpretation the
WD-Trig bit has to be set to “0” to avoid false trigger conditions.
