I have read on here that there have been issues with some Wiz Ethernet devices not releasing the SPI bus correctly when they are no longer selected by the chip select. I am just wondering if the WIZ812MJ is one of these devices, or if it does behave correctly?
I am just desigining a circuit to plug the WIZ812MJ into, and so would like to know if I have to add a transistor or anything to a pin to enable this to work correctly.
I have seen the Freetronics ethernet shield which corrects this problem, however it looks like they switch the SEN pin which doesnt appear to be broken out on the WIZ812MJ's pins. Is the issue fixed already or do I need to do something?
Can anyone assist please?
