Chapter 48 CAN (FlexCAN)
The complete memory map for a FlexCAN module is shown in the following table.
The address space occupied by FlexCAN has 128 bytes for registers starting at the
module base address, followed by embedded RAM starting at address 0x0080.
Each individual register is identified by its complete name and the corresponding
mnemonic. The access type can be Supervisor (S) or Unrestricted (U). Most of the
registers can be configured to have either Supervisor or Unrestricted access by
programming the SUPV bit in the MCR Register. These registers are identified as S/U in
the Access column of Table 48-2.
The registers IFLAG2 and IMASK2 are considered reserved space depending on the
number of Mailboxes available in the device.
