7.17 Cursor Control register (CRSR_CTRL, RW - 0xFFE1 0C00)

The CRSR_CTRL register provides access to frequently used cursor functions, such as

the display on/off control for the cursor, and the cursor number.

If a 32x32 cursor is selected, one of four 32x32 cursors can be enabled. The images each

occupy one quarter of the image memory, with Cursor0 from location 0, followed by

Cursor1 from address 0x100, Cursor2 from 0x200 and Cursor3 from 0x300. If a 64x64

cursor is selected only one cursor fits in the image buffer, and no selection is possible.

Similar frame synchronization rules apply to the cursor number as apply to the cursor

coordinates. If CrsrFramesync is 1, the displayed cursor image is only changed during the

vertical frame blanking period. If CrsrFrameSync is 0, the cursor image index is changed

immediately, even if the cursor is currently being scanned.

The contents of the CRSR_CTRL register are described in Table12–276.

7.18 Cursor Configuration register (CRSR_CFG, RW - 0xFFE1 0C04)

The CRSR_CFG register provides overall configuration information for the hardware

cursor.

The contents of the CRSR_CFG register are described in Table12–277.
