The control byte consists of a 4-bit control code, 3-bits of chip/block select and one direction bit. The
control code is 1010b. For single byte addressing EEPROMs, the chip/block select bits are used for
address bits 10, 9, and 8. For double byte addressing EEPROMs, the chip/block select bits are set
low. The direction bit is set low to indicate the address is being written.
