We would like to configure the button press time of SNVS Power Key in our custom iMX6 board. For this, we tried to access the 'BTN_PRESS_TIME' bits available in SNVS_LPCR Register but we are not able to update the register. Reference Manual states that these bits are read/write accessible but the Security Reference Manual states these bits are reserved.
Are those bits in SNVS_LPCR are read/write accessible ? Is there anyother way to disable the SNVS Power Key?
