3.11 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.

1 Data in Typical column was characterized at 3.0 V, 25C or is typical recommended value.
2 When MCG is configured for FEE or FBE mode, input clock source must bedivisible using RDIV to within the range of 31.25 kHz to 39.0625 kHz.
3 When MCG is configured for PEE or PBE mode, input clock source must be divisible using RDIV to within the range of 1 MHz to 2 MHz.
4 This parameter is characterized and not tested on each device. Proper PC board layout porcedures must be followed to achieve specifications.
