When the serial interface is selected (P/S=“L”), then D7
serves as the serial data input terminal (SI) and D6 serves as
the serial clock input terminal (SCL). At this time, D0 to D5 are
set to high impedance.
When the chip select is inactive, D0 to D7 are set to high
impedance.

This is the external input reference voltage (VREF) for the
internal voltage regulator. It is valid only when external VREF
is used. VEXT must be ³ 2.4V and £ VDD2. When using
internal VREF, this pad must be NC.
