a. "X" indicates the state of this field is a don't care.
b. In this mode, half-word accesses are used. A0 is the LSB of the address and is equivalent to the internal Cortex-M3 A1
address. This pin should be connected to A0 of 16-bit memories.
c. When an entry straddles several row, the signal configuration is the same for all rows.
d. The clock signal is not required for this mode and has unspecified timing relationships to other signals.
