IRQ and on-chip debug
I have an external CS8900 ethernet controller that generates a level
interrupt when data is available. The controller is connected to EXINT0 on
the Oki ML67Q5003. I have configured this interrupt source as a high level
interrupt. Interrupts are being received and processed while the processor
However, the 5003 appears to miss the external interrupt if asserted while
the processor is halted. When the processor is unhalted, the interrupt
handler is not called, even though the interrupt level is asserted. Anyone
run across this issue?
Btw, I am working on an open hardware and open software VoIP phone using the
Oki ML67Q5003 that some of you may find useful for example schematics or
