3.11
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
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.

Data in Typical column was characterized at 3.0 V, 25°C or is typical recommended value.
When MCG is configured for FEE or FBE mode, input clock source must be divisible using RDIV to within the range of 31.25 kHz to
39.0625 kHz.
See crystal or resonator manufacturer’s recommendation.
This parameter is characterized and not tested on each device.
Proper PC board layout procedures must be followed to achieve specifications.
