1.3 Power & I/O level selection
The ES51970 provide a flexible I/O level setting for different MPU system configuration.
The uP_VCC should be connected to the same potential of external Vcc of MCU. The
uP_VCC is allowed to be set between DGND ~ V+. The IO_CTRL pin selects the Vss level
of MCU. If IO_CTRL is set to DGND, the Vss level of MCU is the same as DGND. If
IO_CTRL is set to V-, the Vss level of MCU is the same as V-.
