Cursor 1 X-Position Sign Bit
This bit provides the sign bit of a signed 12-bit value that specifies the horizontal position of cursor
1. The magnitude bits are provided by the Cursor 1 X-Position Low Register (XRA4) and bits 2-0
of this register.
Reserved
These bits always return the value of 0 when read.
Cursor 1 X-Position Magnitude Bits 10-8
These three bits provide the three most significant magnitude bits of a signed 12-bit value that
specifies the horizontal position of cursor 1. The eight least significant magnitude bits of this value
are provided by bits 7-0 of the Cursor 1 X-Position Low Register (XRA4). The sign bit is provided
by bit 7 of this register.
Cursor 1 Y-Position Magnitude Bits 7-0
This register provides the eight least significant magnitude bits of a signed 12-bit value that
specifies the vertical position of cursor 1. 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 1 Y-Position High Register
(XRA7).
