here visualized. Pin H_A_sel is mapped on address pin H_A[7] of the host. The
timing is of course not to scale. When the base address is written, multiple accesses
can be done whereby the different LSB addresses are mapped on pins H_A[6:1]. In
this way a burst of 64 Hwords can be read or written to the same address. The 16 bits
base address can be read when H_A_sel is logic 1 and the signal H_RWn indicates a
read operation. In SAD16_03 mode there is in principle no handshake available.
Therefore, to read data a double read must be done.
