10.7 Crystal Oscillator Timing
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 is set to
clock input. In this situation only, parameter values must be adjusted for the duty cycle at XTAL. DCAOE

3. This is the minimum time required after the PLL set up is changed to ensure reliable operation.
should be used to determine the actual time of each parameter. The terms in this equation are defined as:
Crystal Start-up time
Resonator Start-up time
Crystal ESR
Crystal Peak-to-Peak Jitter
Crystal Min-Max Period Variation
Resonator Peak-to-Peak Jitter
Resonator Min-Max Period Variation
Bias Current, high-drive mode
Bias Current, low-drive mode
Quiescent Current, power-down mode

= Fixed portion of the delay, due to on-chip path delays
= Period of the system clock, which determines the execution rate of the part
= Fixed portion of a clock period inherent in the design; this number is adjusted to account
