(4) Y/BL signal select function

This function is used to select either Y or BL signal output from the Y/BL pin.

Y/BL signal select register (1 bit)...........BLCS (Bit7 in ORP6S)

“0”

......... Y signal output

“1”

......... BL signal output

Y signal............. Output in all OSD areas (Logical OR for R, G, B data

as character data, fringing data, area data, etc.)

BL signal .......... When EXBL is “0”:

Output in all display character areas

(except for character code 000H: Blank character)

When EXBL is “1”:

Output in the whole page

(5) I signal function select

When PISEL (Bit6 in ORETC) is set to “1” and PIDS (Bit3 in ORP6S) is set to “0”,

Port 57 (I pin) can be used as half transparency/half tone through an extra circuit.

At half transparency/half tone function, contents of IDT (Bit3 in ORDSN) is

make no sense. Therefore character color are limited to 8 colors.

Similarly background color, fringing color, raster plane color and area plane

color are limited to 8 colors.

When PISEL (Bit6 in ORETC) sets to “0” and, PIDS (Bit3 in ORP6S) set to “0”,

15 colors to be selectable.

(6) R, G, B, Y/BL Internal/external signal select.

Selects either R, G, B, and Y/BL signals from the internal OSD circuit, or RIN,

GIN, BIN, and Y/BLIN signals from external input.
