Reference voltage output for digital For attaining stabilization, connect this terminal to
DVSS terminal through a capacitance of 10μF or higher (C
REF).
And please do not use this terminal output for the drive purpose of an external circuit.
Serial data output
Serial data are outputted from this terminal when CSN pin is "L" level. This terminal becomes
high-impedance state when CSN pin is "H". Since it is an open drain output pin, pull it up
connected. Do not allow output current of 1.5mA or over.
