5. Adjustment Command
5.1. Adjustment Command(LENGTH=84)
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. E 2 PROM 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 : E2PROM 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 vZideo 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)
