To calculate, use the following w1, w2, and w3 values during sequencer write and the following r1 and r2 values during sequencer read:
w1: 0 for “no write wait” mode; 1 for “1 write wait” mode; 2 for “2 write wait” mode
w2: 1.5 for “no write wait” mode; 2 for “1 write wait” mode; 3 for “2 write wait” mode
w3: 0.5 for “no write wait” mode; 1 for “1 write wait” mode; 1 for “2 write wait” mode
r1: 1.5 for “no read wait” mode; 2 for “1 read wait” mode; 3 for “2 read wait” mode
r2: 0.5 for “no read wait” mode; 1 for “1 read wait” mode; 1 for “2 read wait” mode
