1 Put a series resistor on the baseboard in this case to avoid input/output conflict between RESET_DONE (output/boot

default) and RIC# (input/configuration default).

External interrupts The NS9210 Processor Module provides access to four external interrupts signals, which are multiplexed with other functions on the GPIO pins. Every interrupt is multiplexed to two or three different GPIO pins. These duplicate signals are marked as (dup) in the GPIO table.
