Mini-FlexBus Timing Specifications
A multi-function external bus interface called Mini-FlexBus is provided with basic functionality to interface to slave-only
devices up to a maximum bus frequency of 25.1666 MHz. 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.
All processor bus timings are synchronous; that is, input setup/hold and output delay are given in respect to the rising edge of
a reference clock, MB_CLK. The MB_CLK frequency is half the internal system bus frequency.
The following timing numbers indicate when data is latched or driven onto the external bus, relative to the Mini-FlexBus output
clock (MB_CLK). All other timing relationships can be derived from these values.
