Cursor 2 Y-Position Low Register
Cursor 2 X-Position High Register
This bit provides the sign bit of a signed 12-bit value that specifies the horizontal position
of cursor 2. The magnitude bits are provided by the Cursor 2 X-Position Low Register
(XRAC) and bits 2-0 of this register.
These bits always return the value of 0 when read.
These three bits provide the three most significant magnitude bits of a signed 12-bit value
that specifies the horizontal position of cursor 2. The eight least significant magnitude bits
of this value are provided by bits 7-0 of the Cursor 2 X-Position Low Register (XRAC). The
sign bit is provided by bit 7 of this register.
This register provides the eight least significant magnitude bits of a signed 12-bit value that
specifies the vertical 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 Y-
Position High Register (XRAF).
