(4) Area plane function

Area plane function is used to display square area to two points on a screen.

Two planes operate independently. They are displayed according to the priority

(Area plane 1

> Area plane 2).

See area plane display position setting in section 2.15.5.3 (2) how to set display

positions for each area.

Each area plane is set to ON or OFF by AON2 and AON1 (Bit5 and bit4 in

ORRCL).

Area plane colors are set by ACLIx, ACLRx, ACLGx, ACLBx (Bit7 to bit0 in

ORACL, x: 1, 2).

Area plane colors: 8 or 15

Area plane specification unit: plane

Area plane color specification register (8 bit)

Area plane 1: ACLI1/ACLR1/ACLG1/ACLB1 (Bit3 to 0 in ORACL)

Area plane 2: ACLI2/ACLR2/ACLG2/ACLB2 (Bit7 to 4 in ORACL)

I signal function select: PISEL (Bit6 in ORETC)

“0”

......... 15 colors specification

I pin can be used to make a half level of R, G, B signal (Dark

color) through an extra circuit.

“1”

......... 8 colors specification

Contents of ACLI1 and ACLI2 register is disregarded.

I pin can be used as half transparency/half tone through an

extra circuit.
