Could someone brefiely explain what and how the TX and RX buffers are on a pic and how one accesses them using PBP.
I'm interested in this because I want to connect multiple pics together so that they can comunicate with each other. I wanted to try useing i2c bus but I do not fully understand the slave mode function of it. It doesn't sound like microchip does either. haha.
Just a brief explanation would be greatly appreciated.

Thanks
