(6) High-impedance output control registers 0, 1 (HZA0CTL0, HZA0CTL1)
The HZA0CTL0 and HZA0CTL1 registers are 8-bit registers that control the high-impedance state of the output
buffer.
These registers can be read or written in 8-bit or 1-bit units. However, the HZA0DCFn bit is a read-only bit and
cannot be written.
16-bit access is not possible.
Reset sets these registers to 00H.
Software can be used to always write the same value to the HZA0CTLn register.
The relationship between detection factor and the control registers is shown below.

When TOAB1T1 to TOAB1T3 are output
When TOAB1B1 to TOAB1B3 are output
TOAB1OFF/INTP16 HZA0CTL0
When TOAA11 is output TOAA1OFF/INTP09 HZA0CTL1
Caution High impedance control is performed only when the target port is specified as a target pin in the
above table.
