8. Pin State Table
Explanation of the meaning of words and phrases used in the pin state table according to the chosen mode.
• Input enable: It is possible to input a signal to the device.
• Input fixed: To prevent leakage by floating inputs, the input level is fixed to "0" internally.
• Hi-Z: The pin is put in a high impedance state.
• State hold: The state (input/output) of the pin immediately before changing the state is maintained. In case
of output, the output value of the pin is maintained.
