AC Electrical Characteristics
Notes:
1.
2.
In the following timing diagrams (Figure 2-14 through Figure 2-18), the controls pins are drawn as
active low. Pin polarity is programmable.
3.
The Read Data Strobe is HRD in the Dual Data Strobe mode, HDS in the Single Data Strobe mode.
4.
This timing must be adhered to only if two consecutive reads from one of these registers are executed.
5.
The Last Data Register is the register at address $7, which is the last location to be read or written in
data transfers.
6.
The Write Data Strobe is HWR in the Dual Data Strobe mode, HDS in the Single Data Strobe mode.
7.
The Data Strobe is HRD or HWR in the Dual Data Strobe mode, HDS in the Single Data Strobe mode.
8.
These timings are periodically sampled and are not 100% tested.
9.
The Host Request is HREQ in the Single Host Request mode, HRRQ and HTRQ in the Double Host
Request mode.
10. In this calculation, the host request signal is pulled up by a 4.7 k
W resistor in the Open Drain mode.
