Hi Kevin, I am working on handling six interrupts
sourced by Port-1 pins 18-23. The interrupts are configured as Falling
Edge. The interrupts are generated by a 50% duty
cycle square wave signals on those pins. These signals starts one after the other
and have the same frequency (they never occur at the same time). I can control the generation of these
signals. The interrupt is successfully triggered if
I generate the wave on a single channel (P1.23) , but when I add a wave on
another pin (P1.22), no interrupt triggered at all. I have configured the correct activity type
using “set_irq_type” API, and verified it in the registers. Blow are some of the
registers configuration read from the MCU: Reg Address | Value 40008000 -> 3015a203 40010000 -> 02000100 40008004 -> 00080000 40010004 -> 607b66c4 4000800c -> 3ff0efe0 4001000c -> 821810c0 40008010 -> 00000000 40010010 -> 02000100 40008014 -> c0000000 40010014 -> 00000000 40028138
