CAN Subsystem
44.3.5.2 Register map
The M_CAN module allocates an address space of 256 bytes. All registers are organized as
32-bit registers. The M_CAN is accessible by the Host CPU via the Generic Slave Interface
using a data width of 8-bit (byte access), 16-bit (half-word access), or 32-bit (word access).
Note: Write access by the Host CPU to registers/bits marked with "P=Protected Write" is possible
only when the bit 1 [CCE] and bit 0 [INIT] of the CCCR register is set to "1".
There is a delay from writing to a command register until the update of the related status
register bits due to clock domain crossing.
