Cursor 1 Y-Position High Register
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 Y-Position Low Register
(XRA6) and bits 2-0 of this register.
These bits always return the value 0 when read.
These three bits provide the three most significant magnitude bits of a signed 12-bit value
that specifies the vertical position of cursor 1. The eight least significant magnitude bits of
this value are provided by bits 7-0 of the Cursor 1 Y-Position Low Register (XRA6). The
sign bit is provided by bit 7 of this register.
