RANDOM BYTE READ
Setting bit[11] = 1, bit[12:18] = starting address, the following is the first read
data. After reading back the first data byte, master issues Stop bit.
INDEX BLOCK READ PROTOCOL
Master can stop reading any time by issuing the stop bit without waiting
until Nth byte (byte count bit30-37).
