System Features
5.1.2
SBC Normal Mode
The SBC Normal Mode is the standard operating mode for the SBC. All configurations have to be done in SBC
Normal Mode before entering a low-power mode (see also
Chapter 5.1.6
for the device configuration defining
the Fail-Safe Mode behavior). A wake-up event on CAN, LINx and WKx will create an interrupt on pin INT -
however, no change of the SBC mode will occur. The configuration options are listed below:
•
VCC1 is active
•
VCC2 can be switched ON or OFF (default = OFF)
•
VCC3 is configurable (OFF coming from SBC Init Mode; as previously programmed coming from SBC Restart
Mode)
• CAN is configurable (OFF coming from SBC Init Mode; OFF or wake capable coming from SBC Restart Mode,
see also
Chapter 5.1.5
)
•
LIN is configurable (OFF coming from SBC Init Mode; OFF or wake capable coming from SBC Restart Mode,
see also
Chapter 5.1.5
)
• HS Outputs can be switched ON or OFF (default = OFF) or can be controlled by PWM; HS Outputs are OFF
coming from SBC Restart Mode
•
Wake pins show the input level and can be selected to be wake capable (interrupt)
•
Cyclic sense can be configured with HS1...4 and Timer1 or Timer 2
•
Cyclic wake can be configured with Timer1 or Timer2
•
Watchdog is configurable
•
All FOx outputs are OFF by default. Coming from SBC Restart Mode FOx can be active (due to a failure event,
e.g. watchdog trigger failure, VCC1 short circuit, etc.) or inactive (no failure occurred)
In SBC Normal Mode, there is the possibility of testing the FO outputs, i.e. to verify if setting the FO pin to low
will create the intended behavior within the system. The FO output can be enabled and then disabled again
by the microcontroller by setting the
FO_ON
SPI bit. This feature is only intended for testing purposes.
