3.5.7.1 FlexBus clocking
The system provides a dedicated clock source to the FlexBus module's external
CLKOUT. Its clock frequency is derived from a divider of the MCGOUTCLK. See
Clock Distribution for more details.
3.5.7.2 FlexBus signal multiplexing
The multiplexing of the FlexBus address and data signals is controlled by the port control
module. However, the multiplexing of some of the FlexBus control signals are controlled
by the port control and FlexBus modules. The port control module registers control
