    Default Re: Third Approache - MSSP Module with PBP and ASM Send and Receive Routine

    This is great stuff. I use the MCP23016, but this new IC is much faster.

    Can you explain how you came up with the 3us delay in the 3rd approach? I look at your comment and the SPI characteristics in the datasheet and don't know what to use exactly.
