1. Write Start Address to H_MEM_ADDR_HIGH (8'hf0), H_MEM_ADDR_MID (8'hf1), and _MEM_ADDR_LOW

(8'hf2).

2. Write BL(Burst Length) to H_MEM_ADDR_BL (8'hf3). The BL is programmable between and 63.

The default value of the H_MEM_ADDR_BL when reset is 1.

3. Send command 8'h50 (i.e. Transfer address of the H_MEM_READ).

(16bits per 1 burst, each burst is MSB first.)
