Hi Cory,

thank you for your reply.
Maybe, the SX18 or 16C54 are not laudable members of the PIC familiy. I looked only on it because its impressive 50MIPS.
But I stopped this not only because the awkward programming.

The main reason was the extremely expensive entry point (SX-key for 800.00DM !). I think, only to sniff on a new micro a 99.00$ limit must be enough.

The 2. reason, I found no way to avoid loosing interrupts !
And every micro, which can loose interrupts is forbidden for me.
