Character code (JIS) correspond to initial address of font data as shown below. The table shows
initial address in 20 bits as A19 to A0.
Character code (JIS) are indicated by b7 to b0.
Structure of Korean
<2-byte download>
Font data for 1 character is configured as the figure below.
1 character font data requires 72 + 32 = 104 bytes.
All characters are registered into the section of 1 to 93 and assigning 94 characters in each section
Section1: A1A1H to A1FEH
Section2: A2A1H to A2FEH
:
Section93: FDA1H to FDFEH
Initial address of font data can be calculated by the formula below when representing first byte and
second byte of character code as K1 and K2 respectively.
Initial address =
（（
K1 - A1H
）×
94 +
（
K2 - A1H
））×
104
Example: Obtaining for initial address B5A4H
（（ B5H - A1H ）× 94 + （ A4 - A1H ））× 104
= （ 14H × 94 + 3H ）× 104
= 2FCF8H
Address: Font data of 104 bytes from the address of 2FCF8H are registered
