Fail Outputs
Explanation of FO/GPIO states:
• configurable: settings can be changed in this SBC mode
• fixed: settings stay as configured in SBC Normal Mode
• active: FOx is activated due to a failure leading to SBC Restart or Fail-Safe Mode.
Restart Behavior:
The behavior during SBC Restart and Fail-Safe Mode as well as the transition to SBC Normal Mode is as follows:
• if configured as Wake Input: it will stay wake capable during SBC Restart Mode and OFF while in SBC Fail-
Safe Mode. It will resume wake capability when leaving SBC Restart Mode (SPI register is not modified)
• if configured as Low-Side or High-Side: They will be disabled during SBC Restart and Fail-Safe Mode. After
leaving SBC Restart Mode the previously configured function will be resumed (SPI register is not modified)
• if configured as FO and activated due to a failure: FO will stay activated during SBC Restart Mode and when
entering SBC Normal Mode (SPI register is not modified)
Note:
In order to avoid unintentional entry of SBC Development Mode care must be taken that the level of
FO3/TEST is HIGH during device power up and SBC Init Mode.
Note:
The FOx drivers are supplied via VS. However, the GPIO HS switches (FO2, FO3/TEST) are supplied by
VSHS
