MD[31 : 0]
I/O
CMOS
Memory data bus
These lines are a 32-bit bus for DRAM, and can be switched to function as a 16-
bit bus by setting control register values.
This data bus is also used for video BIOS reads when a PCI bus connection is
used. In that case, the MD[15:0] lines are used as the BIOS ROM address and the
MD[23:16] lines are used as the BIOS ROM data inputs.

Level
Function
BACKON
I/O
CMOS
Back light on
Outputs a signal that requests that the backlight be turned on.
Low: Backlight off
High: Backlight on
This pin can also be used as a general-purpose I/O port.
In external RAMDAC mode, this pin is set to the output state and is used as the
register write signal to the RAMDAC.
LCDON
I/O
CMOS
LCD drive power supply on
Outputs a signal that requests that the LCD panel drive power supply be turned on.
Low: LCD drive power supply off
High: LCD drive power supply on
This pin can also be used as a general-purpose I/O port.
In external RAMDAC mode, this pin is set to the output state and is used as the
register address bit 0 signal to the RAMDAC.
LOGICON
I/O
CMOS
LCD logic power supply on
Outputs a signal that requests that the LCD panel logic system power supply be
turned on.
Low: LCD logic system power supply off
High: LCD logic system power supply on
This pin can also be used as a general-purpose I/O port.
In external RAMDAC mode, this pin is set to the output state and is used as the
register address bit 1 signal to the RAMDAC.
LP
O
Latch pulse
Pulse output that indicates the latch timing for one line of data for an STN LCD
panel. This output is used as the horizontal synchronizing signal when a TFT
LCD panel is used or in external RAMDAC mode.
FP
O
Frame pulse
Pulse output that indicates the frame start for an STN LCD panel. This output is
used as the vertical synchronizing signal when a TFT LCD panel is used or in
external RAMDAC mode.
