Command Block Address. These bits indicate the starting location of the Command Block.
3.1.10 BC Command Block Initialization Count Register (Read/Write)-Register 10
This register contains the number of command blocks that will be initialized when using the auto-initialize feature. If 0000 (hex)
is written into this register, then NO blocks will be set up. Because each Command Block requires eight contiguous memory locations,
the largest value allowed in this register is 1FFF (hex). If a larger value is written into this register, the SBC ignores the three most
significant bits.
