Description

CC Control Register

Fields

INIT

Initialization (read/write)

0 (DISABLED): Normal operation.

1 (ENABLED): Initialization is started.

CCE

Configuration Change Enable (read/write, write protection)

0 (PROTECTED): The processor has no write access to the protected configuration registers.

1 (CONFIGURABLE): The processor has write access to the protected configuration registers (while MCAN_CCCR.INIT = ‘1’).

ASM

Restricted Operation Mode (read/write, write protection against ‘1’)

0 (NORMAL): Normal CAN operation.

1 (RESTRICTED): Restricted operation mode active.

CSA

Clock Stop Acknowledge (read-only)

CSR

Clock Stop Request (read/write)

0 (NO_CLOCK_STOP): No clock stop is requested.

1 (CLOCK_STOP): Clock stop requested. When clock stop is requested, first INIT and then CSA will be set after all pend-ing transfer requests have been completed and the CAN bus reached idle.

MON

Bus Monitoring Mode (read/write, write protection against ‘1’)

0 (DISABLED): Bus Monitoring mode is disabled.

1 (ENABLED): Bus Monitoring mode is enabled.

DAR

Disable Automatic Retransmission (read/write, write protection)

0 (AUTO_RETX): Automatic retransmission of messages not transmitted successfully enabled.

1 (NO_AUTO_RETX): Automatic retransmission disabled.

TEST

Test Mode Enable (read/write, write protection against ‘1’)

0 (DISABLED): Normal operation, MCAN_TEST register holds reset values.

1 (ENABLED): Test mode, write access to MCAN_TEST register enabled.

CME

CAN Mode Enable (read/write, write protection)

0 (ISO11898_1): CAN operation according to ISO11898-1 enabled

1 (FD): CAN FD operation enabled

CMR

CAN Mode Request (read/write)

0 (NO_CHANGE): No mode change

1 (FD): Request CAN FD operation

2 (FD_BITRATE_SWITCH): Request CAN FD operation with bit rate switching

3 (ISO11898_1): Request CAN operation according ISO11898-1

FDO

CAN FD Operation (read-only)

FDBS

CAN FD Bit Rate Switching (read-only)

TXP

Transmit Pause (read/write, write protection)
