Signal T
CK
is defined as 0.5 t
CKIN
. The ADMCF340 uses an input clock with
a frequency equal to half the instruction rate; a 10 MHz input clock (which is
equivalent to 100 ns) yields a 50 ns processor cycle (equivalent to 20 MHz).
When T
CK
values are within the range of 0.5 t
CKIN
period, they should be
substituted for all relevant timing parameters to obtain specification value as
in the following example:
