BYTE READ METHODS (CHOSE ONE):
Use IDT OneCycle Index Block Read, bit[20:27] = 10000001.
Notice that byte count register (byte 8) will be changed to 0IH.
Use Index Block Write protocol to change byte count (byte 8) to
1. After that, use Index Block Read.
TO CHANGE BYTE 8 VALUE:
Use IDT OneCycle Index Block Read, as above
Use Index Block Write protocol to change byte 8 value.

NOTE:
1. Bit [21:27] = byte count.
Bit 20 = 1, bit [21:27] will be stored into SMBus table, Byte 8. SMBus Byte 8 is read
byte count register, power on default is 0FH.
Bit 20 = 0, normal SMBus operation.
BYTE WRITE METHODS:
Setting bit[11:18] = starting address, bit [20:27] = 01H.
