This is the POR reset signal (active LOW) for the entire device, controlled by the MCU_PORz HW Pin.
When LOW, it performs a POR reset on the entire device (MCU and MAIN domains) and puts all IOs in a safe state (Reset/HHV state).
All modules in MCU domain are reset.
MCU IOs are in High-Heating-Value (HHV) state (Reset State).
When MCU_PORz is de-asserted, MCU IOs will enter the default state defined in the device Datasheet. MCU domain will be reconfigured by the R5FSS (secondary boot loader).
All modules in the MAIN domain are reset.
MAIN domain IOs are in HHV state (reset state).
When MCU_PORz is de-asserted, the MAIN domain IOs will enter default state as defined in the device Datasheet.
The R5FSS (secondary boot loader) will setup M4FSS as Safety or General-Purpose Processor.
