5.2 EEPROM DATA READ
(1) Signal Table
(2) Command Set
* 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 : E
2
PROM Slave Address(A0,A2,A4,A6,A8), Not
00h(Reserved by BufferToEEPROM)
ADL : E
2
PROM Sub Address(00~FF)
Data : Write data
(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
E2PROM.
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)
