9.3.2.3 nFAULT Pin

nFAULT is a logic-level output signal, referenced to VIO, from the TCAN1463-Q1 to a CAN FD controller. The nFAULT output is driven to the VIO level as logic-high output.

The nFAULT output is used to transmit the TCAN1463-Q1 status indicator flags to the CAN FD controller. Please see Table 9-1 for the specific fault scenarios that are indicated externally via the nFAULT pin. The TCAN1463-Q1 puts the nFAULT pin in the high-impedance state in the Sleep mode to conserve power because there are no fault scenarios that are indicated externally in the Sleep mode.
