(4) Local Offset Register (LCOR)
Offset:
H'0CC
Initial Value: Undefined
The local offset register (LCOR) is a 32-bit read-only register which indicates the offset
coordinates.
The upper word indicates the X coordinate (XO) of the offset and the lower word indicates the Y
coordinate (YO) of the offset.
LCOR retains its value at a reset.
(5) System Clipping Area MAX Register (SCLMAR)
Offset:
H'0D0
Initial Value: Undefined
The system clipping area MAX register (SCLMAR) is a 32-bit read-only register which indicates
the maximum values of the system clipping coordinates. The upper word indicates the maximum
value of the system clipping X coordinate (SXMAX) and the lower word indicates the maximum
value of the system clipping Y coordinate (SYMAX). The unused bits are always read as 0. When
setting this register by the WPR command, set the maximum values of the drawing range (Max.
4095. SXMAX < DSTRR).
SCLMAR retains its value at a reset.
(6) User Clipping Area MIN Register (UCLMIR)
Offset:
H'0D4
Initial Value: Undefined
The user clipping area MIN register (UCLMIR) is a 32-bit read-only register which indicates the
minimum values of the user clipping coordinates. The upper word indicates the minimum value of
the user clipping X coordinate (UXMIN) and the lower word indicates the minimum value of the
user clipping Y coordinate (UYMIN). The unused bits are always read as 0. When setting this
register by the WPR command, set UXMIN and UYMIN in the following ranges: 0 ≤ UXMIN ≤
UXMAX ≤ SXMAX ≤ 4095, 0 ≤ UYMIN ≤ UYMAX ≤ SYMAX ≤ 4095.
UCLMIR retains its value at a reset.
