2.3.18.3 Cursor-Control Register (Index 06 hex)
The cursor-control register is used to control various on-chip cursor functions of the palette. It can be
accessed by the MPU at any time. Bit 7 of the cursor-control register corresponds to data bus bit 7.

DESCRIPTION
CCR7
0: Nonplanar
Cursor format control. Default is nonplanar for TVP3025 mode operation.
Planar mode is BT485 like operation.
1: Planar
CCR6
0: Disable (default)
Sprite-cursor enable. This bit enables (logic 1) or disables (logic 0) the
64

CCR5
0: (default)
Dual-cursor format. This bit specifies the intersection of the crosshair cursor
and the 64 x 64 cursor. See Section 2.3.9.5.

Section 2.3.9.2.
1: X-windows
CCR3
0: Color 0 (default)
Crosshair color selection. This bit specifies whether the crosshair cursor is to
be displayed in color 1 (logic 1) or color 0 (logic 0).
1: Color 1
CCR2
0: Disable (default)
Crosshair cursor enable. This bit specifies whether the crosshair cursor is to
be displayed (logic 1) or not displayed (logic 0).

CCR1 CCR0
CCR1, CCR0
00: 1 pixel (default)
Crosshair thickness select. These bits specify the width in pixels of the
horizontal and vertical crosshairs when the crosshair cursor is displayed The
horizontal and vertical crosshairs when the crosshair cursor is displayed. The
segments are centered about the value in the cursor-position (x,y) registers.

NOTE: If BT485 command register 2 is written to (or at reset in the BT485 mode), cursor-control register bits 2 and 5
are set to logic 0.
If BT485 command register 4 is written to (or at reset in the BT485 mode), cursor-control register bit 7 is set to
logic 1.
In the BT485 mode, the following BT485 command register bits are written into the following cursor-control
register bits: CR20 into CCR4, CR21 into CCR6.
