NOTE:
1.
X means “don’t care”, H means logic HIGH. L means logic LOW.
2.
All inputs except SSOE# must meet setup and hold times around the rising edge (LOW to
HIGH) of SSCLK.
3.
For a write operation following a read operation, SSOE# must be HIGH before the input data
required setup time plus High-Z time for SSOE# and staying HIGH thoughout the input data
hold time.
4.
This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
