(1) This signal must be kept 0 if device power supplies are not valid during RTC mode and 1 during normal operation. This can typically be
achieved by connecting rtc_iso to the same signal driving porz (not rtc_porz) with appropriate voltage level translation if necessary.

sys_nirq1
DESCRIPTION
Non maskable interrupt input, active-low. This pin can be optionally routed to the
DSP NMI input or as generic input to the ARM cores. Note that by default this pin
has an internal pulldown resistor enabled. This internal pulldown should be disabled
or countered by a stronger external pullup resistor before routing to the DSP or
ARM processors.
