NOTES:
The exposed die attach pad
must
be connected to a solid ground plane as this is the main ground connection for the
chip.
Note that digital inputs
SCLK
,
SI
and
CSn
are high-impedance inputs (no internal pull-up) and should have external
pull-ups if not driven.
SO
is high-impedance when
CSn
is high. An external pull-up should be used at
SO
to prevent
floating input at microcontroller.
