10.8 Crystal Oscillator Timing
10.9 External Memory Interface Timing
The External Memory Interface is designed to access static memory and peripheral devices.
Figure 10-4
shows sample timing and parameters that are detailed in
Table 10-16
.
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:
t = D + P * (M + W)
should be used to determine the actual time of each parameter. The terms in this equation are defined
as:
t
= Parameter delay time
D
= Fixed portion of the delay, due to on-chip path delays
P
= Period of the system clock, which determines the execution rate of the part
(i.e., when the device is operating at 60MHz, P = 16.67 ns)
M
= Fixed portion of a clock period inherent in the design; this number is adjusted to account
for possible derating of clock duty cycle
W
= Sum of the applicable wait state controls. The “Wait State Controls” column of
Table 10-16
shows the applicable controls for each parameter and the EMI chapter of the
56F8300 Peripheral User Manual
details what each wait state field controls.
When using the XTAL clock input directly as the chip clock without prescaling (ZSRC selects
prescaler clock and prescaler set to
÷
1),
the EMI quadrature clock is generated using both edges
of the EXTAL clock input. In this one situation parameter values need to be adjusted for the duty
