56F8346 Technical Data
Preliminary
cycle at XTAL. DCAOE and DCAEO are used to make this duty cycle adjustment where needed.
DCAOE and DCAEO are calculated as follows:
The timing of write cycles is different when WWS = 0 than when WWS > 0. Therefore, some
parameters contain two sets of numbers to account for this difference. Use the “Wait States
Configuration” column of
Table 10-16
to make the appropriate selection.
Figure 10-4 External Memory Interface Timing
Note:
When multiple lines are given for the same wait state configuration, calculate each and then
select the smallest or most negative.
DCAOE =
=
0.5 - MAX XTAL duty cycle, if ZSRC selects prescaler clock and the prescaler is set to
÷
1
0.0 all other cases
MIN XTAL duty cycle - 0.5, if ZSRC selects prescaler clock and the prescaler is set to
÷
1
0.0 all other cases
Example of DCAOE and DCAEO calculation:
Assuming prescaler is set for
÷
1 and prescaler clock is selected by ZSRC, if XTAL duty cycle
ranges between 45% and 60% high;
DCAEO =
=
DCAOE = .50 - .60 = - 0.1
DCAEO = .45 - .50 = - 0.05
