#174662 - Thanks Jan
Responding to: ???'s previous message
Thanks for your reply.
I will definitely have a look at PCA Cookbook. And as always, I prefer to do it on my own, rather than a pre-cooked solution. Because, you can judge, if anything goes wrong, then there is no "Grey" area left in your product.

Try to come up with something on your own. Is the Rx connected to a pin which can trigger an interrupt? What is the crystal frequency? Is this a 12-clok or a 6-clock derivative? Can your application tolerate interrupts with higher priority than those which are used now?


No, RX is connected to P1.2, not to an interrupt. I can try using a device having 2 serial ports, but, those are very costly and I do not have a programmer to program them.

Crystal is 24 MHz.
CPU can be used as a 6-clock, but I prefer using in 12-Clock mode. But, if required, I can configure it for 6-clock mode.
Yes, the UART can be used to have a higher priority than the other interrupt.
