Power supplies and MXI must be stable before the start of tW(RESET)..

Pin reset behavior depends on which peripheral defaults to controlling the multiplexed pin. For more details on what

pin group (e.g., Z Group, Z/Low Group, Z/High Group, etc.) each pin belongs to, see Section 6.5.8, Pin Behaviors at
