SUBJECT [Question] 5. How can we test interface between MCU and W3100A-LF?
NAME WIZnet DATE 2007-05-25 HIT 2937
1. Check if you can read written value from the common register of the W3100A-LF. For example, once you wrote 0x80 at SIP register, you have to be able to read the value there.
2. Check TX/RX memory using Memory Test Command.
3. Check if an interrupt occurs using the SYS_INIT command.
4. Read from Cx_ISR register and check if the register is cleared.
5. Write 0xFF into IR and check if the register is cleared.
