Hello, i builded at a board based on a PDIUSB12 USB controller and
9s12e64 uC (i choose the Hc12 uC is because i can debug it pretty easil with the BDM interface) I used as a trace the code fro
formatting link
that was intended for PDIUSBD11. I think that my board is electrically ok:the D12 responds correctly t commands as Set_Clk_Out,Soft connect and so on..
The problem is that during enumeration i read from the D12 an Irq value o
0x03 or 0x83, the low nibble=3 indicates that the bits indicating CTRL_I interrupt and CTRL-OUT interrupt are both set,and this sounds like a no sense,the host can't require a byte and in the same time have a byte t send.The two pins D0 and D1 are not shorted,i verified they can hav different levels Thank you for any help,or just for read this Diego Milano
