Cursor 2 Control Register
0: Disables blinking. This is the default after reset.
1: Enables blinking. Blinking rate set in register FR19.
0: Disables vertical stretching for cursor 2. This is the default after reset.
1: Enables vertical stretching for cursor 2.
Note: Just as is the case with the vertical stretching for the main display image, vertical
stretching for cursor 2 applies only to flat panel displays.
0: Disables horizontal stretching for cursor 2. This is the default after reset.
1: Enables horizontal stretching for cursor 2.
Note: Just as is the case with the horizontal stretching for the main display image,
horizontal stretching for cursor 2 applies only to flat panel displays.
0: Selects the outermost upper left-hand corner of the screen border as the origin for the
coordinate system used to position cursor 2. This is the default after reset.
1: Selects the upper left-hand corner of the active display area as the origin for the
coordinate system used to position cursor 2.
0: Disables the vertical extension feature for cursor 2. This is the default after reset.
1: Enables the vertical extension feature for cursor 2, thereby permitting the height of
cursor 2 may be specified independently of its mode selection through the use of the Cursor
2 Vertical Extension Register (XRA9).
These three bits select the mode for cursor 2. See appendix F for more details concerning
the cursor modes.
