i.MX6dq GPIO Interrupt status register unable to clear

[Hariharan1]

Hi all,

I am using GPIO4_IO31 pin eventually i used for touch event that gpio. while configuring gpio interrupt trying to clear gpio interrupt status register
*(volatile uint32_t*)0x20a8018  = 0x80000000

but i have got that register value 0xffee8bff.

I configure level sensitive and selected edge level for sensitive mode. what could be reason for this problem. 

Thanks for advance,

Hariharan
