Example for a Read Access, with One Data Byte Transferred via DOUT
The data transfer is synchronized by the DCLK input. The contents of DIN is latched at
the rising edge of DCLK, while DOUT changes with the falling edge of DCLK. During
execution of commands that are followed by output data (read commands), the device
will not accept any new command via DIN. The data transfer sequence is completed by
setting CS to high.
To reduce the number of connections to the
together, and form a bi-directional data-‘pin’.
For special applications a byte by byte transfer is needed. This can be done by
prolonging the high time of DCLK for a user defined ‘waiting time’ after transferring any
byte.
