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.

FDOE

CAN FD Operation Enable (read/write, write protection)

0 (DISABLED): FD operation disabled.

1 (ENABLED): FD operation enabled.

BRSE

Bit Rate Switching Enable (read/write, write protection)

0 (DISABLED): Bit rate switching for transmissions disabled.

1 (ENABLED): Bit rate switching for transmissions enabled.

PXHD

Protocol Exception Event Handling (read/write, write protection)

EFBI

Edge Filtering during Bus Integration (read/write, write protection)

TXP

Transmit Pause (read/write, write protection)

NISO

Non-ISO Operation
