Functional bits reset diagram All functional registers following either the power up or the soft reset will load the default value from OTP or fixed value when the PF09 is starting a full Power-up sequence, that includes: 1. Transition from the DBGOFF into the Power-up sequence 2. Device performs a hard reset Only functional registers following the soft reset will be able to reload the default value when a soft reset occurs. provides a list of register characteristics following a soft reset.: Bit Name Description Reset Value Condition FCCU1_RESET Reset on FCCU1 0x00 No reset (only FS0B) Cleared on Soft-Reset, MCU must re- configure the safety reaction.
