Error Count Disable Bit

Enables or disables the TEC and REC to be functional.

0: TEC and REC function according to CAN specification

1: TEC and REC is disabled to function (count value is

retained, enabled only in test mode)

DRXIN

R/W

HRXD Pin Input Enable

Enables or disables the HRXD pin to be supplied into the

CDLC.

0: Input from the CAN bus to the HRXD pin is enabled

1: Input from the CAN bus to the HRXD pin is disabled

(enabled only in test mode)

• When INTLE = 0, the HRXD pin always holds

recessive data.

• When INTLE = 1, data is input from the internal HTXD

to the HRXD pin.

DTXOT

R/W

HTXD Pin Output Enable

Enables or disables the HTXD pin to output the CAN bus.

0: Output from the HTXD pin to the CAN bus is enabled

1: Output from the HTXD pin to the CAN bus is disabled

(enabled only in test mode)

• When INTLE = 0, the HTXD pin always outputs

recessive data to the CAN bus.

• When INTLE = 1, the internal HTXD outputs data to

the internal HRXD.

INTLE

R/W

Internal Loop Enable

Enables or disables connection between the internal

HTXD and internal HRXD.

0: Internal HRXD is supplied from the HRXD pin

1: Internal HRXD is supplied from the internal HTXD

(enabled only in test mode)
