Display Controller Register Descriptions
6.6.6.3
DC Memory Offset 68h
Type
Reset Value
This register contains the X position information of the hardware cursor.
6.6.6.4
DC Memory Offset 6Ch
Type
Reset Value
This register contains status information for the current display state, including the current scan line for the display
(V_LINE_CNT, bits [26:16]). This portion of the register is read only and is used by software to time update the frame buffer
to avoid tearing artifacts. This scan line value is driven directly off of the DOTCLK, and consequently it is not synchronized
with the CPU clock. Software should read this register twice and compare the result to ensure that the value is not transi-
tioning.
This register also contains the line count at which the lower screen begins in a VGA split-screen mode (SS_LINE_CMP).
When the internal line counter reaches this value, the frame buffer address is reset to 0. This function is enabled with the
SSLC bit in the DC_DISPLAY_CFG register (DC Memory Offset 08h[13]).
Several additional read only display status bits are provided to allow software to properly time the programming of registers
and to detect the source of display-generated interrupts.

Description
Cursor Y. This field represents the Y coordinate of the line at which the upper left corner
of the cursor is to be displayed. This value is referenced to the screen origin (0,0) which
is the pixel in the upper left corner of the screen.
Description
Reserved. Write as read.
Icon X. This field represents the X coordinate of the pixel at which the upper left corner of
the icon is to be displayed. This value is referenced to the screen origin (0,0) which is the
pixel in the upper left corner of the screen. The full pattern of the icon must be displayed.
