Elan Digital Systems Ltd. 19 AD125 USER’S GUIDE
3.4.3 ENABLING TRIGGER
The AD125 will not trigger unless Bit 1 of SETUP REG 1 is low.
This allows software to “arm” the AD125 only when it is
appropriate to do so i.e. after some start up condition or when the
user has signalled that the system should arm ready to capture an
event.
