• Assembler: Meaning of Rn,Rt,Rm etc.

    HenkvW
    HenkvW

    Hi,

    All assembler instructions (examples) refer to registers as Rn, Rm, Rt etc.

    I cannot find some explanation of this .n, .m, .t letters.

    I searched the complete Assembler helpfile and all Programming pdf's.

    Who can help me out? Thanks,

    Can anyone assist with the availability of a USB component that allows
    communication with the USB device. The same as a RS232 component can connect
    and communicate with a RS232 device. But for USB devices.
