the synchronization signal is obtained starting from electrical position information (EL_POS
register) according to following
Table 19.
ALARM_EN
The ALARM_EN register allows selecting which alarm signals are used to generate the
FLAG output. If the respective bit of ALARM_EN register is set high, the alarm condition
forces the FLAG pin output down.
Table 20.
