Part Number: TDA4VM

Hello,

e2e.ti.com/.../processor-sdk-dra8x-tda4x-gpio-interrupt

why is 178(CSLR_R5FSS0_CORE0_INTR_GPIOMUX_INTRTR0_OUTP_18) here, I understand it is 176(CSLR_R5FSS0_CORE0_INTR_GPIOMUX_INTRTR0_OUTP_16).

Why calculate like this?

Hi,

Can you please refer to below link? As per this link, the output 16 of GPIO mux is directly connected to R5F interrupt 176 and there are such 16 interrupts, which can be directly connected to the R5F..
