MDMA mode
[1]
T
cy1
is the total cycle time, consisting of command active time t
w1
and command recovery (inactive) time t
w2
, that is, T
cy1
= t
w1
+ t
w2
. The
minimum timing requirements for T
cy1
, t
w1
and t
w2
must all be met. As T
cy1(min)
is greater than the sum of t
w1(min)
and t
w2(min)
, a host
implementation must lengthen t
w1
and/or t
w2
to ensure that T
cy1
is equal to or greater than the value reported in the IDENTIFY DEVICE
data. A device implementation shall support any legal host implementation.
