52 / 73 page ![]() Programming manual L6482 52/73 Doc ID 023768 Rev 2 The synchronization signal is obtained starting from the electrical position information (EL_POS register), according to Table 25: 9.1.17 ALARM_EN The ALARM_EN register allows the selection of which alarm signals are used to generate the FLAG output. If the respective bit of the ALARM_EN register is set high, the alarm condition forces the FLAG pin output down. Table 24.
