FlexCAN clocking and MCAN clocking provides options to configure the bit time segments, as shown in
the figure below. The column on the right-hand side of the diagram shows the breakdown, in
nanoseconds, of a CAN bit time, as configured by the FlexCAN or MCAN.

LFAST clocking
The LFAST is the third module that has its own tab. It is a versatile, but intricate module that hosts its
own PLL which generates multiple phases and generates a signal within specification only if its inputs
are certain frequencies. These intricacies make it necessary to give LFAST its own dedicated tab.
LFAST clocking presents a block diagram of the module with various clocks going into it. It also
supports LFAST_PLL configuration to increase the LFAST frequency up to 480 MHz. The LFAST also
