Last SCK sampling edge to HREQ output
not deasserted (CPHA = 1)
SS deassertion to HREQ output not
deasserted (CPHA = 0)
SS deassertion pulse width (CPHA = 0)
HREQ in assertion to first SCK edge
HREQ in deassertion to last SCK sampling
edge (HREQ in set-up time) (CPHA = 1)
First SCK edge to HREQ in not asserted
(HREQ in hold time)
HREQ assertion width
V
Periodically sampled, not 100% tested.
All times assume noise free inputs.
All times assume internal clock frequency of 200 MHz.
SHI_1 specs match those of SHI.
