In the timing diagrams below, the controls pins are drawn as active low. The pin
polarity is programmable.

The read data strobe is HRD in the dual data strobe mode and HDS in the single data
strobe mode.
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.
This timing is applicable only if a read from the “last data register” is followed by a
read from the RXL, RXM, or RXH registers without first polling RXDF or HREQ
bits, or waiting for the assertion of the HOREQ signal.
7.
This timing is applicable only if two consecutive reads from one of these registers are
executed.
8.
The write data strobe is HWR in the dual data strobe mode and HDS in the single data
strobe mode.
9.
The data strobe is host read (HRD) or host write (HWR) in the dual data strobe mode
and host data strobe (HDS) in the single data strobe mode.
10. The host request is HOREQ in the single host request mode and HRRQ and HTRQ in
the double host request mode.
11. In this calculation, the host request signal is pulled up by a 4.7 k
Ω
resistor in the
open-drain mode.
