These bits always return the value of 0 when read.
Cursor 2 Base Address Bits 21-16
These six bits provide the six most significant bits of a 22-bit value that specifies the offset from the
beginning of the frame buffer memory space where the 4KB cursor data space for cursor 2 is to be
located. The four next most-significant bits of this 22-bit value are supplied by the Cursor 2 Base
Address Low Register (XRAA).
Cursor 2 X-Position Magnitude Bits 7-0
This register provides the eight least significant magnitude bits of a signed 12-bit value that
specifies the horizontal position of cursor 2. The three most significant magnitude bits and the sign
bit of this value are provided by bits 2-0 and bit 7, respectively, of the Cursor 2 X-Position High
Register (XRAD).
