SYNC operation mode
The pin works as a synchronization signal when the SYNC_EN bit is set high. In this mode a
step-clock signal is provided on the output according to a SYNC_SEL and STEP_SEL
parameter combination (see
FLAG pin
By default an internal open drain transistor pulls the FLAG pin to ground when at least one
of the following conditions occur:

It is possible to mask one or more alarm conditions by programming the ALARM_EN
register (see
condition is masked and it does not cause a FLAG pin transition; all other actions imposed
by alarm conditions are performed anyway. In the case of daisy chain configuration, the
FLAG pins of different ICs can be OR-wired to save host controller GPIOs.
