ZHCSFQ2C November 2016 – June 2018 TUSB422
PRODUCTION DATA.
This register is used to indicate a status change event. When a status change event occurs and its corresponding Alert mask is unmasked, the TUSB422 will assert the INT_N low. The INT_N remains asserted until all events are cleared by write of 1’b1. Once all events are cleared or corresponding Alert mask is masked, the INT_N will be de-asserted high.
