The device incorporates four external reset pins (MCU_PORz, MCU_RESETz, PORz, and RESET_REQz) and four reset status pins (MCU_PORz_OUT, MCU_RESETSTATz, PORz_OUT, and RESETSTATz). These pins can be driven by an external power good circuitry or Power Management IC (PMIC). MCU_PORz and Main PORz pins should be held active low during the entire power-up phase, and until all power supplies as well as the HFOSC0 clock are stable.
All MCU domain resets act as master resets to the whole device, whereas Main domain resets only reset Main domain (MCU domain is reset isolated from all Main domain resets).
