Memory Map/Register Definition
41.3.2 Module Configuration Register (CANx_MCR)
This register defines global system configurations, such as the module operation modes
and the maximum message buffer configuration.
Addresses: CAN0_MCR is 4002_4000h base + 0h offset = 4002_4000h

Module Disable
This bit controls whether FlexCAN is enabled or not. When disabled, FlexCAN disables the clocks to the
CAN Protocol Engine and Controller Host Interface sub-modules. This is the only bit in MCR not affected
by soft reset.

1
Freeze Enable
The FRZ bit specifies the FlexCAN behavior when the HALT bit in the MCR Register is set or when
Debug Mode is requested at MCU level. When FRZ is asserted, FlexCAN is enabled to enter Freeze
Mode. Negation of this bit field causes FlexCAN to exit from Freeze Mode.
0
1
Rx FIFO Enable
This bit controls whether the Rx FIFO feature is enabled or not. When RFEN is set, MBs 0 to 5 cannot be
used for normal reception and transmission because the corresponding memory region (0x80-0xDC) is
used by the FIFO engine as well as additional MBs (up to 32, depending on CTRL2[RFFN] setting) which
Enable the FlexCAN module.
Disable the FlexCAN module.
Not enabled to enter Freeze Mode
