Basic Operation in Hi-Z Control for Asynchronous Inputs
(a)
Hi-Z Control when TAPAnCTL0.TAPAnDCM = 0, TAPAnDCP = 1, and
TAPAnDCN = 0
TAPAnTHZOUT0 goes to the low level on detection of a valid edge of the
asynchronous input (TAPAnTHASIN).
Output is forcibly stopped (by port control for Hi-Z output) as long as the
TAPAnTHZOUT0 output is at the low level.
TAPAnTHZOUT0 goes to the low level in response to detection of a rising
edge of the asynchronous input (TAPAnTHASIN).
TAPAnTHZOUT0 goes to the high level in response to writing 1 to Hi-Z stop
trigger 0 (TAPAnOPHT0), regardless of the level of TAPAnTHASIN.
