6.1 Introduction
6.2 Fail-safe system controller
The UJA1061 combines all peripheral functions around a microcontroller within typical
automotive networking applications into one dedicated chip. The functions are as follows:
The fail-safe system controller is the core of the UJA1061 and is supervised by a
watchdog timer that is clocked directly by the dedicated on-chip oscillator. The system
controller manages the register configuration and controls all internal functions of the
SBC. Detailed device status information is collected and presented to the microcontroller.
The system controller also provides the reset and interrupt signals.
The fail-safe system controller is a state machine. The different operating modes and the
transitions between these modes are illustrated in
further details about the SBC operating modes.
