    Hi,

    By default, microwire memory has separate DI and DO rail.
    But some ICs can use DI as single SDIO rail by connecting DO to DI via 10-100k resistor.

    Does OpenProg handles microwire programming through single SDIO rail?
    How to connect RB0 and RC7 on hardware level to allow direct SDIO programming?

    Single SDIO is not microwire; maybe you mean UNIO or onewire

    Thanks for reply.

    I mean TC9WMC2 (Toshiba).
    In Data Sheet there is chapter 3. "Notes on Use" (page 10).
    "(3) Erroneous detection of a start bit" - an example of joined SIO bus in microwire interface.

    In principle you can join DI and DO, no change to protocol or any command, but I never tried.
    The device anyways has two pins, so why not using the standard connection?
