Notes:
1. Chip Select must be brought low for a minimum of 250ns (t
) betweenconsecutive instruction cycles.
2. The Clock frequency specificationcalls for a minimum clock period of 1
μ
s, therefore the sum of the timings t
CHCL
+ t
CLCH
must be greater or equal to 1
μ
s. For example, if t
CHCL
is 250ns, then t
CLCH
must be atleast 750ns.
3. This is preliminary data.
