When debugging the Ethernet-example for the MBC167CR-NET evaluation board, the following situation occurs: The CS8900 very nicely generates an interrupt (P2.15=CAPCOM15), but the interrupt routine is not executed! Following is the setup: IEN=1 CC15IE=1 CC15MODE=0x03 (Trig on rising edge) The "interrupt sytem"-view in UV2, confirms that CC15IR is set when P2.15 rises (upon a "PING" released from a connected PC). Any suggestions to why the interrupt-function (supplyed by the sample SW) isn't executed? /Anders Bech
