The target pin can output a signal when the HZA0DCM0 bit = 0, regardless of the
Setting the HZA0DCC0 bit to 1 is invalid if a level indicating an abnormality
The HZA0DCC0 bit is always 0 when it is read.
Setting the HZA0DCT0 bit to 1 is invalid when the HZA0DCE0 bit = 0.
Setting the HZA0DCT0 and HZA0DCC0 bits simultaneously to 1 is prohibited.

A target pin in the high-impedance state is enabled by using software to
output a signal and the HZA0DCF0 bit is cleared to 0.
Indicates that a target pin is enabled to output.
Indicates that a target pin is in a high-impedance state.

Cleared (0) when the HZA0DCC0 bit = 1.
Set (1) when the HZA0DCT0 bit = 1.
Set (1) if a level indicating an abnormality (detected according to the setting
of the HZA0DCN0 and HZA0DCP0 bits) is input to the TW0TOFFP pin.
