External Interface Timing Characteristics
Table 12 lists processor bus input timings.
NOTE
All processor bus timings are synchronous; that is, input setup/hold and output delay with
respect to the rising edge of a reference clock. The reference clock is the FB_CLK output.
All other timing relationships can be derived from these values. Timings listed in Table 12
are shown in Figure 11 and Figure 12.

5.6.1
FlexBus
A multi-function external bus interface called FlexBus is provided with basic functionality to interface to slave-only devices up
to a maximum bus frequency of 80MHz. It can be directly connected to asynchronous or synchronous devices such as external
boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no additional circuitry. For
asynchronous devices a simple chip-select based interface can be used. The FlexBus interface has six general purpose
chip-selects (FB_CS[5:0]) which can be configured to be distributed between the FlexBus or SDRAM memory interfaces.
8
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal.
Noise injected into the PLL circuitry via PLL VDD, EVDD, and VSS and variation in crystal oscillator frequency increase
the Cjitter percentage for a given interval.
9
Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of Cjitter+Cmod.
10 Modulation percentage applies over an interval of 10
μs, or equivalently the modulation rate is 100kHz.
11 Modulation range determined by hardware design.
