(4) Transitioning to the high-impedance output state by using the HZA0DCT0 bit
To set the pin to the high-impedance output state by using the HZA0DCT0 bit, the HZA0DCT0 bit must be set (1)
while the trigger signal is in the inactive-level state. When not using the trigger signal (HZA0DCN0 = HZA0DCP0 = 0),
however, the high-impedance output state can be entered by setting (1) the HZA0DCT0 bit.
(a) HZA0DCN0 = 0 and HZA0DCP0 = 1, or HZA0DCN0 = 1 and HZA0DCP0 = 0
<1> Set (1) the HZA0DCT0 bit (generate the high-impedance output instruction signal).
<2> Read the HZA0DCF0 bit and check the flag status.
<3> If HZA0DCF0 = 1, return to operation <1>. The level of the trigger signal must be checked.
If HZA0DCF0 = 0, the high-impedance output state is entered.
(b) HZA0DCN0 = HZA0DCP0 = 0
Set (1) the HZA0DCT0 bit (the high-impedance output instruction signal is generated -> the high-impedance
output state is entered).
