(4) Blinking function

Blinking function is used to blink display characters.

When BKMF is “1”, characters specified for blinking by BLF are not displayed.

(If the background color function is used, the background color is not

disappeared.)

Blinking specification unit: Character

Blinking specification register (1 bit) ....... BLF (Bit4 in ORDSN)

“0”

......... No blinking

“1”

......... Blinking

Blinking master specification register (1 bit) ...... BKMF (Bit5 in ORETC)

“0”

......... Disable blinking

“1”

......... Enable blinking (Characters whose BLF are set to “1” are not

displayed.)

Note:

Regarding the extra dot of the left and/or right character by fringing function, it

is not enabled as blink.

(5) Underline function

Underline function is used to add a line under a display character. The

underline is same color as that of character.

Underline specification unit: Character/line

Underline enable register (Character unit) (1 bit) ..... EUL (Bit5 in ORDSN)

“0”

......... No underline

“1”

......... Underline

Underline enable register (Line unit) (1 bit

× 12) ...... EULAn (n: 1 to 8)(OREULA8),

EULAn (n: 9 to 12)

(OREULA12)

Underline colors: 8 or 15

Underline color specification registers (4 bits)

...... RDT, GDT, BDT, IDT (Bit3 to 0

in ORDSN)

(Refer to Table 2.15.5.9)

Note:

To use the underline function, set both the underline enable register for

underlining text in characters and that for underlining text in lines. If the former
