(a) Setting procedure
(i) Setting of high-impedance control operation
(ii) Changing setting after enabling high-impedance control operation
(iii) Resuming output when pins are in high-impedance state
(iv) To make the pin to go into a high-impedance state by software
<1> Set the HZAyDCMn, HZAyDCNn, and HZAyDCP1 bits.
<2> Set the HZAyDCEn bit to 1 (enable high-impedance control).
<1> Clear the HZAyDCEn bit to 0 (to stop the high-impedance control operation).
<2> Change the setting of the HZAyDCMn, HZAyDCNn, and HZAyDCP1 bits.
<3> Set the HZAyDCEn bit to 1 (to enable the high-impedance control operation again).
If the HZAyDCMn bit is 1, set the HZAyDCCn bit to 1 to clear the high-impedance state after the valid
edge of the external pin
this bit is set while the input level of the external pin
<1> Set the HZAyDCCn bit to 1 (command signal to clear the high-impedance state).
<2> Read the HZAyDCFn bit and check the flag status.
<3> Return to <1> if the HZAyDCFn bit is 1. The input level of the external pin
The HZAyDCTn bit must be set to 1 by software to make the pin to go into a high-impedance state
while the input level of the external pin
the setting is not dependent upon the setting of the HZAyDCMn bit.
<1> Set the HZAyDCTn bit to 1 (high-impedance output command).
<2> Read the HZAyDCFn bit to check the flag status.
<3> Return to <1> if the HZAyDCFn bit is 0. The input level of the external pin
However, if the external pin
pin goes into a high-impedance state when the HZAyDCTn bit is set to 1.
Note HZA0CTL0: TOQH0OFF pin, HZA0CTL1: TOP2OFF pin, HZA1CTL0: TOQ1OFF pin,
The pin can function as an output pin if the HZAyDCFn bit is 0.
The pin is in a high-impedance state if the HZAyDCFn bit is 1.
HZA1CTL1: TOP3OFF pin
