TDA4VH-Q1: Do I need to configured a clock in Mcu to trigger a GPIO interrupt ?

Miguel Flores

Part Number: TDA4VH-Q1

Tool/software:

Hello, I would like to konow if I need to configure a clock in the Mcu to feed WKUP_GPIO if I want to trigger an interrupt on pin state change for WKUP_GPIO0_3.

Also, I would like know if this correct interrupt source that I have to use: 124 (WKUP_GPIOMUX_INTRTR0_OUTP_0)

And one last thing, the interrupt service routine is configured per PIN or per bank ?

I don't want the interrut routine to be triggered if WKUP_GPI0_0 or WKUP_GPIO0_4 change state.

Hello,

yes you can use it,if not used elsewhere.

It is per bank, you need to read the register of the bank and get the status of individual pin to confirm.

Hello, I have the PIN WKUP_GPIO0_5 configured as MCU_MCAN1_RX (MuxMode 0u). As this pin is not configured as WKUP_GPIO (MuxMode 7u) it means that any change in this pin is not going to trigger the interrupt, right ?

This interrupt is only triggered by pins configured as GPIOs regardless if they are part of the same bank.

Yes if it configured to be MCAN then it is no longer GPIO.
