Hello,
I am working on a embedded product. In that we are using AM186CH as =
the host and RTL8019AS as the Ethernet controller. I am having a problem =
, since the AM186CH is not having a interrupt controller which is 8259 =
compatible. As the reason the interrupt controller in AM186CH will not =
generate Interrupt Acknowledge Signal (IACK) to the device that had =
interrupted, Instead if the controller will jump to the corresponding =
interrupt vector if it service the interrupt request.Inorder to notify =
the RTL regarding the service of it's interrupt request, if i reset the =
corresponding interrupt bit in the Interrupt status register of the RTL =
will the RTL will treat it as interrupt acknowledge or it will aware =
that it's interrupt request to AMD is serviced by the host. Can anybody =
help me in this regard.
with regards,
sriramkumar. R
