Bit 20:
PSTYLE
Description
0
Pattern style disabled (Initial value)
1
Source pattern is created based on the destination coordinates
Notes: 1. Set the source offset TXOFS and TYOFS to 0.
2. Clear this bit to 0 when the source style specification bit (STYLE) is 0.
3. Clear the source address specification bit (SS) to 0.
4. Clear this bit to 0 for commands other than the POLYGON4A and POLYGON4B
commands.
5. This bit is not decoded by a command so it must be set or cleared in each relevant
command.
Bits 19 and 18—Pattern X Size (PXSIZE): These bits specify the pattern X size when the
pattern style enable (PSTYLE) bit is 1.
Bit 19:
PXSIZE[1]
Bit 18: PXSIZE[0]
Description
0
0
Pattern X size = 8 pixels

Note: Set the specified pattern X size (8, 16, 32, or 64) in the source size TDX.
Bits 17 and 16—Pattern Y Size (PYSIZE): These bits specify the pattern Y size when the
pattern style enable (PSTYLE) bit is 1.
Bit 17:
