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