System timer module (STM)
The STM implements the following features:
 Up-counter with 4 output compare registers
 OS task protection and hardware tick implementation per AUTOSAR(a) requirement
The STM is replicated for each processor.
Software watchdog timer (SWT)
This module implements the following features:
 Fault tolerant output
 Safe internal RC oscillator as reference clock
 Windowed watchdog
 Program flow control monitor with 16-bit pseudorandom key generation
 Allows a high level of safety (SIL3 monitor)
The SWT module is replicated for each processor.
Fault collection and control unit (FCCU)
The FCCU module has the following features:
 Redundant collection of hardware checker results
 Redundant collection of error information and latch of faults from critical modules on
the device
 Collection of self-test results
 Configurable and graded fault control
– Internal reactions (no internal reaction, IRQ, Functional Reset, Destructive Reset,
or Safe mode entered)
– External reaction (failure is reported to the external/surrounding system via
configurable output pins)
System Integration Unit Lite (SIUL)
The SIUL controls MCU reset configuration, pad configuration, external interrupt, general
purpose I/O (GPIO), internal peripheral multiplexing, and system reset operation. The reset
configuration block contains the external pin boot configuration logic. The pad configuration
block controls the static electrical characteristics of I/O pins. The GPIO block provides
uniform and discrete input/output control of the I/O pins of the MCU.
