GPIO signals must be configured through software for input, output, bidirectional, or open-drain. Some GPIO have one or more

alternative use modes, which are also software-configurable. The reset default for all GPIO signals is as an input signal. Refer to the

DLPC900 Programmer's Guide (DLPU018).

Trigger Control Pin Functions

DESCRIPTION

POWER

NAME

NUMBER

In video pattern mode, this signal is used for advancing the

TRIG_IN_1

AF7

VDD33

Async

pattern display.

In video pattern mode, the rising edge of this signal is used

for starting the pattern display and the falling edge is used

TRIG_IN_2

H25

VDD33

Async

for stopping the pattern display. It works along with the

software start stop command.

TRIG_OUT_1

E20

VDD33

Async

Active high trigger output signal during pattern exposure.

TRIG_OUT_2

D22

VDD33

Async

Active high trigger output to indicate first pattern display.

These signals do not apply to the slave controller in a two controller system configuration. On the slave controller, these pins are

reserved and should be left unconnected. Refer to the Typical Single Controller Chipset and the Typical Two Controller Chipset for a

description between a one controller and a two controller configuration.
