HI Doni and All, Where did you find the infomation about the 8 bit serial (non spi) stating a 20 BPF rate? I have read all the doc's on C54x, bootloader, and any other referance I could find. the only thing I have seen about that is the bootloader doc states a min 40 cpu cycles between frames? I dont question if 20 bits per frame will work, just that it is a fixed number compared to 40 cpu cycles which could happen in two BCLKR's or some much less than 20BPF. I hope to figure out what I have not understood. When I do I will let the group know of my findings. Maybe someone else will be able to make use some day of those findings. Caleb Austin |

You're right, my calculation was based on: BLCKR = 1/2 CPUCLK BFSR = 1/40 CPUCLK ------------------- 1 FRAME = 20 BPF Indeed, if BCLKR is very slow you don't need to have a minimum frame of 20 BPF. --- In , "dsp_man_c54" <austca@b...> wrote: > HI Doni and All, > > Where did you find the infomation about the 8 bit serial (non spi) > stating a 20 BPF rate?
