DIGITAL DRAIN VOLTAGE (VDD)
to the SPI circuit. In the event V
provides power to a portion of the logic, ensuring limited
functionality of the device. All device configuration registers
are reset.
SERIAL OUTPUT (SO)
pin of the MCU or to the SI pin of the next device of a daisy
chain of devices. This output will remain tri-stated (high-
impedance OFF condition) so long as the
is Logic HIGH. SO is only active when the
