The cycle time, high phase time, and low phase time of the SCK clock are
t
CYCLE1
,
t
CH1
and
t
CL1
, all
measured at the 50% level. The rise and fall times of SCK, CMD, and SIO0 are
t
DR1
and
t
DF1
,
measured at the 20% and 80% levels.
The CMD signal is sampled twice per
t
CYCLE1
interval, on the rising edge (odd data) and the falling
edge (even data). The set/hold window of the sample points is
t
S1
/
t
H1.
The SCK and CMD timing
points are measured at the 50% level.
The SIO0 signal is sampled once per
t
CYCLE1
interval on the falling edge. The set/hold window of the
sample points is
t
S2
/
t
H2.
The SCK and SIO0 timing points are measured at the 50% level.
