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.
The host request is HOREQ in the single host request mode and HRRQ and HTRQ in the double host request mode.
In this calculation, the host request signal is pulled up by a 4.7 kΩ resistor in the open-drain mode.
