Notes:
1. Priortoreadingdatafrom(orwritingdatato)theSerialInter-
face, the user is not required to provide a clock signal at the
SCLK. However,shortlybeforeperforminganyreadorwrite
operationswiththeSerialInterface,theusermustsupplythe
clock signal to the SCLK input pin.
2. Each Read or Write operation, with the Serial Interface, will
require 16 SCLK periods, as depicted in Figure 4.
3. UponcompletionofaReadorWritecycle,theusermustne-
gate CSBforatleast250ns(seetimingparameterT29inthe
AC Characteristics), before asserting it again for the next
Read or Write operation.
