First of all thank you for your attention:
I am using Freescale KL25z MCU as master and Wiznet w5500 chip as a slave for my project.
So far I have managed to send and recieve data via wiznet correctly. Thats why there is no problem writing and reading the w5500 chip.
In the next part I have to use interrupt pin in order to operate my system properly.
However, I cannot make the interrupt pin low.
For example when a Recieve signal comes, Sn0_IR becomes 0x05( Connect and Recieve int). Moreover the mask register Sn_IMR is FF. According to datasheet when these 2 registers becomes 1, the INTn pin is asserted to low.
By the way I wrote 100 to INTLEVEL register.
I also checked my system, when the int pin becomes low my system responses correctly. Furthermore there is always high signal seen by looking via scope.
Is there anything that I have missed?
I am waiting for your help
