6.7.2 Registers Controlling High-Impedance Output Controller
Registers used to control the High-Impedance Output Controller are shown below.
 High-impedance output function enable register (HIZTREN)
 High-impedance output mode select register (HIZTRS)
 High-impedance output function control register 0 (HZA0CTL0)
(1) High-impedance output function enable register (HIZTREN)
HIZTREN is a register that enables/disables the input of the trigger signal used for controlling high-impedance output.
HIZTREN can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears HIZTREN to 00H.
