(2) Command Set
* Purpose
1) EDID write : 16-byte by 16-byte, 8 order (128-byte)
write(TO “00 – 7F” of “EEPROM Page A4”).
2) FOS Default write : 16-mode data (HFh, HFl, VF, STD,
HP, VP, Clk, ClkPh, PhFine) write.
3) Random Data write : write the appointment Address of

5.4. VRAM Read
1) Send CMD(70h) to read Video RAM value from MICOM
And save its value to 128-Bytes Buffer.(Common Buffer for
the use of EDID)
the use of EDID)
2) Delay 500ms. (Time to Wait and Read Video RAM from
MICOM)
3) Be transmitted the contents of MICOM’s 128-bytes Buffer to
PC. (128th Data is the CheckSum of 127-bytes data :
That’s OK if the value of adding 128-bytes Data is Zero)
