Hi all,
The C167 has edge based external interrupts (programmable to rising/falling/both). Does anybody have a reference to info on how to interface it with a level based interrupt device (e.g. an external multi-port UART)? When you OR several interrupt sources together, you miss interrupts. What's the "industry standard" way of handling this?
I just checked the datasheet of an XC167 and it also has edge based external interrupts only. Could somebody explain, to a simple software engineer :-), what the advantage of edge based interrupts is? Level based seems to make alot more sense to me; it's plain and simple.
