[TDA4VM] TDA4EVM GPIO Interrupt Generation Problem

Hi, in TDA4 TRM, 12.1.2.4.3 GPIO Interrupt and Event Generation, says that CPU can write GPIO data reg to trigger an interrupt. Since we are doing a real time notification in kernel, this mechanism is what we want. One module(maybe a module on another CPU) write a reg, then irq handler fires.

This is what I do with TDA4 EVM and ti-processor-sdk-linux-automotive-j7-evm-06_01_00_05

1) press SW10 USER1 button on the common processer board

2) cat /proc/interrupts, "GPIO Key USER1" with irq number 139 do has some interrupt event

3) devmem2 0x00600010, shows the GPIO0_0 connected with USER1 button is configured as in direction
4) devmem2 0x00600010 w 0xfffffffe, swith GPIO0_0 to out direction
5) devmem2 0x00600014 w 0x00 && devmem2 0x00600014 w 0x01, to toggle GPIO state
6) cat /proc/interrupts, "GPIO Key USER1" interrupt event counter has no change
7) press SW10 USER1 button
8) cat /proc/interrupts, "GPIO Key USER1", interrupt event counter increased

Would you please give me some hint about how to trigger a local interrupt with a write to GPIO data reg?

Or, is there any other regs that could trigger an interrupt when CPU do some write to them?

Thanks
