read data bursts with different data between one burst and the next one according to
IDD7 Measurement-Loop Pattern table; DM: stable at 0; bank activity: two times
interleaved cycling through banks (0, 1, ...7) with different addressing, see IDD7

Notes: 1. Burst Length: BL8 fixed by MRS: MR0 bits [1,0] = [0,0].
2. MR: mode register
Output buffer enable: set MR1 bit A12 = 1 and MR1 bits [5, 1] = [0,1];
RTT_Nom enable: set MR1 bits [9, 6, 2] = [0, 1, 1]; RTT_WR enable: set MR2 bits [10, 9] = [1,0].
3. Precharge power down mode: set MR0 bit A12= 0 for Slow Exit or MR0 bit A12 = 1 for fast exit.
4. Auto self refresh (ASR): set MR2 bit A6 = 0 to disable or 1 to enable feature.
5. Self refresh temperature range (SRT): set MR0 bit A7= 0 for normal or 1 for extended temperature range.
6. Read burst type: nibble sequential, set MR0 bit A3 = 0.
