I/O

DESCRIPTION(2)

NAME

NUMBER

GPIO_08

G14

General purpose I/O 08 (hysteresis buffer). Options:

(All) Normal mirror parking request (active low): To be driven by the PROJ_ON output of the host. A

logic low on this signal will cause the DLPC3470 controller to PARK the DMD, but it will not power

down the DMD (the DLPA2000 device does that instead). The minimum high time is 200 ms. The

minimum low time is also 200 ms.

GPIO_07

F15

General purpose I/O 07 (hysteresis buffer). Options:

Display: LABB output sample and hold sensor control signal (Output)

Light Control: Reserved for TRIG_OUT_2 signal (Output).

Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used

(otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).

GPIO_06

F14

General purpose I/O 06 (hysteresis buffer). Option:

Light Control: Reserved for pattern ready signal (Output). Applicable in Internal Pattern Streaming

Mode only.

Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used

(otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).

GPIO_05

E15

General purpose I/O 05 (hysteresis buffer). Options:

Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used

(otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).

GPIO_04

E14

General purpose I/O 04 (hysteresis buffer). Options:

3D glasses control (output): intended to be used to control the shutters on 3D glasses (Left = 1, Right

= 0).

SPI1_CSZ1 (active-low output): optional SPI1 device select 1 signal. An external pullup resistor is

required to deactivate this signal during reset and auto-initialization processes.

Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used

(otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).

GPIO_03

D15

General purpose I/O 03 (hysteresis buffer). Options:

SPI1_CSZ0 (active low output): Optional SPI1 device select 0 signal. An external pullup resistor is

required to deactivate this signal during reset and auto-initialization processes.

Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used

(otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).
