A cheap FPGA is lower in cost than the $15US per each at q10K that SiLabs has on its website for their cheapest parts.

It's worth the effort just to get rid of the stupid, Stupid, STUPID requirement to clear the TI and RI flags after writing/reading the SBUF.

It's worth the effort just to put in a synchronous serial port capable of a moderate data rate, e.g. 10 Mbps, that's actually useful for something. SiLabs has eliminated that possibility by limiting the data rate.

It's just a mental masturbation project. By the time it's done, if I live that long, there will be no more commercial 805x's as everything will have been switched to ARM and the like. KEIL/ARM will see to that.

   They do work to a limited extent, but...            01/01/70 00:00      
      there's a range ...            01/01/70 00:00      
         What architecture?            01/01/70 00:00      
            805x, but modified            01/01/70 00:00      
               are you reinventing the wheel?            01/01/70 00:00      
                  Yes, but it's worth the trouble            01/01/70 00:00      
                     wrong place to read            01/01/70 00:00      
                        I only looked at their site once ...            01/01/70 00:00      
                     SiLabs pricing?            01/01/70 00:00      
                        That's what they had on their website            01/01/70 00:00      
   RTFM?            01/01/70 00:00      
      Mostly, it's absence of "TFM"            01/01/70 00:00      
   OP Update            01/01/70 00:00      
   I hate to assume, but            01/01/70 00:00      
      "free" ... I doubt it ...            01/01/70 00:00      
         OK a recollection from a seminar            01/01/70 00:00      
            Maybe from this convention?            01/01/70 00:00      
   is FPGA a suitable "substrate" for a processor?            01/01/70 00:00      
      it's not as easy as the marketeers say ...            01/01/70 00:00      
         FPGA Software            01/01/70 00:00      
      FPGAs work fine for processors for us            01/01/70 00:00      
      FPGA-based processors            01/01/70 00:00      
         Shouldn't it do better than 50 MHz?            01/01/70 00:00      
            50 MHz is pretty fast            01/01/70 00:00      
            My most recent design work            01/01/70 00:00
