FlexCAN
A block diagram describing the various submodules of the FlexCAN module is shown in
Each submodule is described in detail in subsequent sections.
25.1.1
The FlexCAN module address space is split into 128 bytes starting at the base address, and then an extra
256 bytes starting at the base address +128. The upper 256 are fully used for the message buffer structures,
as described in
occupied by various registers.
