DESCRIPTION
Chip Select:
High during write and read operations. Low disables the serial port.
While CS is low, SDO remains in high impedance state, and SDI and
SCK activities are ignored.
Serial Clock:
Controls the timing of SDI and SDO.
Serial Data Input:
Inputs mode and address information. Also inputs register data during
a Write operation. Both address and data are input least significant bit
first.
Serial Data Output:
Outputs register information during a Read operation. Data is output
least significant bit first.
