Bit 24—Destination Transparent Color Polarity (DTP): Selects whether destination
transparency occurs when the destination data and the value set in the destination transparent color
register (DTCR) match or do not match.
Bit 24: DTP
0
1
Description
Destination transparency at a match (Initial value)
Destination transparency at a mismatch
Bit 21—Source Pixel Format (SPF): Specifies the pixel format for the multi-valued source. This
setting is valid only for a multi-valued 16-bit/pixel source. This bit should be cleared to 0 for an 8-
bit-pixel source. Set this bit to match the destination pixel format.
Bit 21: SPF
0
1
Description
RGB = 565 format (Initial value)
ARGB = 1555 format
Bit 20—Destination Pixel Format (DPF): Specifies the pixel format for the destination. This
setting is valid only for a 16-bit/pixel destination. This bit should be cleared to 0 for an 8-bit-pixel
destination. Set this bit to match the multi-valued source pixel format.
Bit 20: DPF
0
1
Description
RGB = 565 format (Initial value)
ARGB = 1555 format
Bit 18—Graphic Bit Mode (GBM): Specifies the graphic bit mode for the multi-valued source
and destination.
Bit 18: GBM
0
1
Description
8-bit/pixel (Initial value)
16-bit/pixel
Bit 17—Source A Value Use (SAU): When the pixel format of the source and destination is the
ARGB format, drawing is performed while referencing the source A value as the destination A
value.
Bit 16—A Value (AVALUE): When the pixel format of the source and destination is the ARGB
format, drawing is performed with the destination A value as 0 or 1.
