26.3.20 Logical Operation Input Data Register for Blitter (GR_LGDAT)
The register GR_LGDAT sets data for logical operation to be performed on the blitter. Since
logical operation is performed after format conversion, data should be specified as 5 bits of
LGDAT_R (R data), 5 bits of LGDAT_G (G data) and 5 bits of LGDAT_B (B data).

Undefined R
Reserved
The read value is undefined. The write value should
always be 0.

R/W Logical Operation Data (α)
These bits set logical operation data (α) = α log.
23 to 21 
Undefined R
Reserved
The read value is undefined. The write value should
always be 0.
20 to 16 LGDAT_R 00000
R/W Logical Operation Data (R)
These bits set logical operation data (R) = Clog_r.
15 to 13 
Undefined R
Reserved
The read value is undefined. The write value should
always be 0.
12 to 8 LGDAT_G 00000
R/W Logical Operation Data (G)
These bits set logical operation data (G) = Clog_g.
7 to 5 
Undefined R
Reserved
The read value is undefined. The write value should
always be 0.
4 to 0 LGDAT_B 00000
R/W Logical Operation Data (B)
These bits set logical operation data (B) = Clog_b.
Note: This register is valid only when the logical operation function has been selected (SBSEL in
GR_BLTMODE = 10)
