Description
VCC3 Output Voltage Configuration (if configured as
independent voltage regulator)
0_B , VCC3 has same output voltage as VCC1
1_B , VCC3 is configured to either 3.3V or 1.8V (depending on
VCC1 derivative)
Soft Reset Configuration
0_B , RO will be triggered (pulled low) during a Soft Reset
1_B , No RO triggering during a Soft Reset
Failure Output Activation (FO1..3)
0_B , FOx not activated by software, FO can be activated by defined
failures (see Chapter 13)
1_B , FOx activated by software (via SPI)
VCC3 VS_UV shutdown configuration
0_B , VCC3 will be disabled automatically at VS_UV
1_B , VCC3 will stay enabled even below VS_UV
VCC3 Configuration
0_B , VCC3 operating as a stand-alone regulator
1_B , VCC3 in load sharing operation with VCC1
Reserved, always reads as 0
VCC3 Load Sharing in SBC Stop Mode configuration
0_B , VCC3 in LS configuration during SBC Stop Mode and high-
power mode: disabled
1_B , VCC3 in LS configuration during SBC Stop Mode and high-
power mode: enabled
Configuration Select (see also Table 5)
0_B , Depending on hardware configuration, SBC Restart or Fail-
Safe Mode is reached after the 2. watchdog trigger failure
(=default) - Config 3/4
1_B , Depending on hardware configuration, SBC Restart or Fail-
Safe Mode is reached after the 1. watchdog trigger failure -
Config 1/2
Notes
1. Clearing the FO_ON bit will not disable the FOx outputs for the case a failure occurred which triggered the FOx
outputs. In this case the FOx outputs have to be disabled by clearing the FAILURE bit.
If the FO_ON bit is set by the software then it will be cleared by the SBC after SBC Restart Mode was entered
and the FOx outputs will be disabled. See also Chapter 13 for FOx activation and deactivation.
