8 PWRDWN/
nFLASH_OUT
1
Output Open drain, 100K pull up on engine; PWRDWN (active high) indication that
the N56XX is in power off mode. nFLASH_OUT (active low) notification when
the unit is exposing. (Operation is menu selectable.)
9 nBEEPER Output Open drain, 100K pull up on engine; idle high signal that can be an active low
DC or PWM controlled AC signal used to drive an external beeper.
10 nGoodRead Output Open drain, 100K pull up on engine; active low signal for driving a low current
Good Read LED circuit.
11 nWAKE Input 100K pull up on engine; when in power off mode active low wake up signal to
the N56XX. Not used in USB - leave floating.
12 nTrig Input/
Output Open drain, weak pull up on engine; Trigger line is an active low signal to
trigger the unit. Leave the signal floating for inactive state and connected to
ground for active state.
