Description

CAN failure - control bit for CAN failure INT (CANH/L to GND, VDD or VSUP, CAN over-current, Driver Over Temp, TXD-PD,

RXD-PR, RX2HIGH, and CANBUS Dominate clamp)

INT disable

INT enable.

MCU req - Control bit to request an INT. INT will occur once when the bit is enable

INT disable

INT enable.

LIN2 fail - Control bit to enable INT when of failure on LIN2 interface

INT disable

INT enable.

LIN/1 fail - Control bit to enable INT when of failure on LIN1 interface

INT disable

INT enable.

I/O - Bit to control I/O interruption: I/O failure

INT disable

INT enable.

SAFE - Bit to enable INT when of: Vaux over-voltage, VDD over-voltage, VDD Temp pre warning, VDD under-voltage(36),

SAFE resistor mismatch, RST terminal short to VDD, MCU request INT.(37)

INT disable

INT enable.

VMON - enable interruption by voltage monitoring of one of the voltage regulator: VAUX, 5 V-CAN, VDD (IDD Over-current, VSUV,

VSOV, VSENSELOW, 5V-CAN low or thermal shutdown, VAUX low or VAUX over-current

INT disable

INT enable.

Notes

36.

If VDD under-voltage is set to 70% of VDD, see bits b6 and b5 in Table 15 on page 68.

37.

Bit 2 is used in conjunction with bit 6. Both bit 6 and bit 2 must be set to 1 to activate the MCU INT request.
