Note: In this example the Burst Configuration Register is set with M2-M0 = 001 (Burst Length = 4 Words or Double Words), M6 = 1 (Valid

Clock Edge = Rising Clock Edge), M7 = 0 or 1 (Burst Type = Interleaved or Sequential), M9 = 0 (Y-Latency = 1), M14-M11 = 0011 (X-

Latency = 8) and M15 = 0 (Read Select = Synchronous Burst Read), other bits are don’t care.
