EEPROM READ E7
* Purpose : To read the appointment Address of
E2PROM by 128(80h)-byte
5.3. E2PROM Data Write
(1) Signal Table
LEN : 84h+Bytes
CMD : 8Eh
ADH : E2PROM Slave Address(A0,A2,A4,A6,A8), Not
00h(Reserved by BufferToEEPROM)
ADL : E2PROM Sub Address(00~FF)
Data : Write data
(2) Command Set
Adjustment contents CMD(hex)
EEPROM WRITE
* 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,
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)
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)
