(5) EEPROM DATA READ
1) Signal TABLE
2) Command Set
* To read the appointment Address of E2PROM by 128(80h)-
byte
(6) EEPROM Data Write(serial number D/L)
1) Signal TABLE
CMD : 8Eh
LENGTH : 84h+Byte
ADH : E2PROM Slave Address (A0, A2, A4, A6, A8),
Not 00h (Reserved by Buffer To EEPROM)
ADL : E2PROM Sub Address (00~FF)
Data : Write data
2) Command Set
* Description
- EDID write : 16-byte by 16-byte, 8 order (128-byte) write
(TO “00 - 7F” of “EEPROM Page A4”)
- FOS Default write : 16-mode data (HFh,HFl,VF,STD,HP,
VP,Clk,ClkPh,PhFine) write
- Random Data write : write the appointment Address of
E2PROM
3) VRAM Read.
- 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)
- Delay 500ms ( Time to Wait and Read Video RAM from
MICOM)
- Be transmitted the contents of MICOM°Øs 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)
10. Set Information(Serial No & Model name)
10-1. check the serial number & Model Name
(1) Push the menu button in DTV mode.
Select the STATION ==> Diagnostics ==> To set
(2) Check the Serial Number
