In
Figure 8
the principle of first writing the base address indicated by H_A_sel is 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.
Remark: The H_waitn signal is synchronized to H_procclock (pin 18). So it depends
on the host used which H_procclock is provided. When the host can accept an
asynchronous H_waitn signal, the clock signal connected to the sys_clk input (pin 21)
can also be used as the clock signal to the H_procclock input.
