Hi,
I am developing dspi code for mcf54452 board. I am communicating processor
with EEPROM (AT25080A) slave device. Write function is working fine. But
the read function is not working.
Write seq:
----------
1. Send WREN command
2. Send write Instruction
3. Send address where to be data written
4. Send data
Note: i checked the write seq by seeing the signals in scope. Every byte
had been sent out (Sout) perfectly.
Read seq:
--------
1. Send read Instruction
2. Send address where from the data to be read.
Note: i checked the read seq by seeing the signals in scope.
1. No SCK signals
2. No DATA (Sin)
3. Chip select in inactive state (high)
I checked with pdfs. i am not getting any solution for this problem.
So can you guide me to solve this problem?
Reply me as soon as possible
Regards,
Karthikeyan.
