7.5.1.10 DESTOP_DMDCTRL Register

The DESTOP_DMDCTRL register can be used in place of the external DLPC910 control inputs to control the

functions described. Bit-0 must be set to “1” to gain control of the functions. Bit-5 is available regardless of the

state of bit-0.

ADDRESS

BITS

DESCRIPTION (1)

RESET

TYPE

0x002C

Enables DMD control of the functions that are normally

0x0

R/W

controlled on external pins.

0 = Controlled from external pins (default)

1 = Controlled from the I2C interface

NS_FLIP. Sets the orientation of the top and bottom of the

0x0

R/W

DMD.

0 = Un-flipped (default)

1 = Flipped

DATA_COMP. Sets a DMD mode that inverts all of the

0x0

R/W

incoming data.

0 = Normal (default)

1 = Data is inverted at the DMD

LOAD_FOUR. Activates the Load4 function of the DMD.

0x1

R/W

Each row written is loaded to 4 consecutive locations.

0 = Load4 mode is active

1 = Normal (default)

RST2BLKZ. Activates the RST2BLKZ function of the DMD.

0x1

R/W

Refer to Table 5 for setting RST2BLKZ.

(1)

When bit 0 is set to 1, bits 1, 2, 3, and 4 override their respective external control inputs.

7.5.1.11 DESTOP_BIT_FLIP Register

The DESTOP_BIT_FLIP register is used for configuring the DLPC910 output LVDS buses to the DMD. To

simplify board layout design, flipping individual buses may reduce routing constraints. If the buses are flipped in

hardware, then the appropriate setting that matches the hardware must be set after a power cycle or a reset to

the DLPC910.

0 = un-flipped (default)

1 = flipped

Reverses the Data bits for bus C (b'15 = b'0, b'0 = b'15)

0x0

R/W

0 = un-flipped (default)

1 = flipped

Reverses the Data bits for bus D (b'15 = b'0, b'0 = b'15)

0x0

0 = un-flipped (default)

1 = flipped
