IOs support HHV mode during power up. HHV is defined as a state when PORz signal is driven LOW.
HHV is an IO Voltage Buffer feature that allows the IO cells to be tri-stated. All IO cells have HHV which is asserted (driven) by HHV generated during PORz assertion. There default pull values during this HHV/PORz assertion for each pin are specified in the device-specific data sheet. All HHV logic controlling the buffer high-impedance control and the associated default pull value will be asynchronous.
For more details on HHV signals, refer to Device Configuration - Power Chapter
