Pin Functions
SERIAL DATA INPUT DI
The DI pin is used for transferring in commands and data
Data is latched on the rising edge of SK
SERIAL DATA OUT DO
The DO pin is used for transferring out status and data Data
output will change following the falling edge of SK
CHIP SELECT CS
This signal indicates which device is selected When this
signal is inactive the device ignores SK This signal can be
tied to ground when there is only one Serial Flash device
The CS pin may be pulled high to reset command input
SERIAL DATA CLOCK SK
This is the standard synchronous MICROWIRE clock which
determines the rate of data transfer On each toggle one
data bit is shifted into or out of the Serial Flash
