Issue when a pin has multiple signals for an ALT mode

[MathisDeroo]

Hi,

I'm currently trying to generate the PAC for MCXA2xx and MCXA5xx devices, based on the json files created.
However on these devices, pins have a analog mode that is selected via ALT0. That means, ALT0 can have multiple signals routed as for P2_3 on MCXA577; ANALOG = ADC0_A3/ADC1_A4/CMP0_INN5/DAC1_OUT/TSI0_CH33 and ALT0 = P2_3.

When running the generator, following issue is triggered :

Completed successfully
2026-03-10T16:34:50.703973Z ERROR generator: Error for output Generating metadata

Caused by:
    pin P2_3 has more than one signal defined for alt mode 0
Error: Failed to generate chips true
error: process didn't exit successfully: `target\debug\generator.exe MCXA577` (exit code: 1)

Can you help modifying the generator to consider that a single pin can be routed to multiple signals ?

Thanks

@i509VCB Could you give some input here? What's your idea for cases like this? ADC function is also achieved via function0 on the mux. How do you want the data to be generated for these cases?

Probably need to remove that (or log overlaps?). That validation check assumed LPC54 and RT1xxx

In different MCUs (TI in this case, alt 0 is shared as well).
