10.8 External Memory Interface Timing
The External Memory Interface is designed to access static memory and peripheral devices.
shows sample timing and parameters that are detailed in
The timing of each parameter consists of both a fixed delay portion and a clock related portion, as well as
user controlled wait states. The equation:
When using the XTAL clock input directly as the chip clock without prescaling (ZSRC selects prescaler
clock and prescaler set to
input. In this situation only, parameter values must be adjusted for the duty 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

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;
DCAOE = .50 - .60 = - 0.1
DCAEO = .45 - .50 = - 0.05
(i.e., when the device is operating at 60MHz, P = 16.67 ns)
