SPI Reset Input: A “low” on this pin resets the device and puts
the part into SPI mode. A logic-high on this pin causes the
device to execute its program if the V
out voltage level.
No Connect. Float Pin.
SPI Data In/Input/Output 0: General-purpose I/O and button
input. In SPI mode, this pin serves as SDI (Serial Data Input).
SPI Data Out/Input/Output 1: General-purpose I/O and button
input. In SPI mode, this pin serves as SDO (Serial Data
Output).
SPI Clock/Input/Output 2: General-purpose I/O and button
input. In SPI mode, this pin serves as SCK (SPI Clock Input).
Crystal/Clock Input: Input to the inverting oscillator amplifier
and input to the internal clock operating circuit. This pin may
be driven externally for test purposes.
