26: This signal has different functions depending on the TQMa8Xx variant. See TQMa8Xx User’s Manual for details.
27: For factory use only, do not contact.
28: If the i.MX 8X internal watchdog of the SCU is to be used as PMIC watchdog interrupt (PMIC_WDI), pins X5-16 (PMIC_WDI) and X5-20 (SCU_WDOG_OUT)
must be connected.
29: Open-Drain Output. Requires external pull-up to supply voltage if used.
30: Reserved for future use.
