39.6.1.11 Offset 000000A0h: RxMessageControl[0-15] - Receive Message
Command and Control
Note:
These registers are implemented in the SRAM which does not have the capability to
mask writes to reserved bits. Therefore, reserved bits in this CSR will be RW. Software
should treat these bits as reserved and not change the reset value of these bits.
Note:
These registers are implemented in SRAM which is not initialized at power-up or upon
reset. So before enabling the CAN, software needs to update these CSR’s with the reset
values.
