** bit0 is transfered with the SPI input word
BUT
the watchdog trigger is set, after readout of
the SPI input bit = CSN LOWto HIGH
(see arrows at CSN signal)
* for the exact timing relations between CSN
and SPI-DI and -DOword please look at
datasheet fig. 11,12,13,14,15
*** for a correct watchdog triggering:
closed window must always exceed 12 cycles
open window is max. 20 cycles
long open window is max. 128 cycles
otherwise
a watchdog reset will be generated
