TRKFAULT

TRK-CAN FAULT

Address:

GLOBAL_BaseAddress + 0x9

Type:

Reset:

0b00000000000000

Description:

TRK-CAN FAULT stores Tracking regulator and CAN interface faults plus echo of CAN and regulators configuration

pins

NOTE: As monitors are working also during startup phases, when voltage levels cannot be stable, it can happen that

some fault bit are set to “1” after POR. To avoid false diagnosis when the device is fully functional, it is suggested to

read this register once after the startup in order to clean it.
