PN7642 GPIO3 does not cause wakeup from ULPCD mode

I am using ULPCD mode in my application. The host needs to wake the PN7642 using GPIO3.

I have tested this but toggling GPIO3 doesn't wake the PN7642 from ULPCD. 

The data sheet says the following:

The following EEPROM configuration is available:
• ULPCD_VOLTAGE_CTRL
• ULPCD_RSSI_GUARD_TIME
• ULPCD_RSSI_SAMPLE_CFG
• ULPCD_THRESH_LVL
• ULPCD_GPIO3 - Allows to abort the ULPCD based on GPIO input.

Is there an example of how to configure GPIO3 in the EEPROM so that it is properly enabled?

Thanks.

Hi Mlang:

 

Could you please let me know how to reproduce this issue with NXP PN7642 EVK board , or only happens on your custom board?

 

Regards

Daniel
