Hi,
I want to read the internal signals inside the psoc1, like GOE or GOO.
I know how to read any input/output pin from the psoc1
does I have to route the GOE to an output pin and then read the output pin
or is there a direct way to read all signals inside the psoc1 ?
thanks.

One way would place digital buffer, config it to interrupt, then route
the GOO buss to a GIE buss then to buffer. Use interrupt to indicate state
of GOO.

No, read the respective registers ( read the register TRM, Technical Reference Manual) -

but these registers GDI_O_IN are for connecting the GOO from output to inputs, it's not to read their value ?
I generate a signal from the digital blocs, and I want to read it without using interrupts, and without outputing it to an external pin
how to do that ?

Are you trying to read the port register, PRTxDR ?

Yes and no. as I said earlier, I know how to read PRTxDR by program
I would like to read the global Outbus Bus without having to route that bus to an output pin.
is this possible with a psoc1 ?
thanks.
