The data sheet includes inaccurate information on the polarity of the POR_TEST signal.
The correct description is a follows:
POR_TEST: Power-on-reset test output; this pin should be a true no connect on the board. POR_TEST is Low during power up and when POR_BYPASS and POR_RESET are asserted High (causing a device reset). After power up is complete, POR_TEST is High when POR_BYPASS is Low, or when POR_BYPASS is High and POR_RESET is Low.
*An internal timer circuit in the POR component determines when to release POR_TEST after power reaches the ON threshold.
