A low level on this pin returns all registers to a known state as indicated
in the section entitled
starts an SPI transaction. The SPI transaction is signaled as completed
when this signal returns high.
This output will be asserted low when an enabled interrupt condition
occurs. It contains a pullup current source that will perform a pullup when
unasserted.
SPI data into this IC. This data input is sampled on the positive edge of
SCLK.
Clocks in /out the data to/from the SPI. MISO data changes on the
negative transition of the SCLK. MOSI is sampled on the positive edge of
the SCLK.
SPI data sent to the MCU by this device. This data output changes on the
negative edge of SCLK. When CS is high, this pin is high impedance.
4.0 MHz clock input.
Ground reference for analog and digital circuits.
