IO HVDD 3 or 2 wire serial interface data IO. When 3 wire (input)
serial is selected, output interface becomes CMOS
type. When 2 wire serial is selected, output interface
becomes open drain type. Please use this pin with
external pull-up resister when 2 wire serial is
selected. If this pin is used with external pull-up
resistor, it possibly gets noise from power. Therefore
tamper noise design is required in the noisy
environment.
