TA1 and TA2 are transfer addresses used to specify read/write locations when moving data to/from the scratchpad. TA1 is only necessary for smaller devices that do not require two bytes to specify a memory start location. Obviously, since you get 256 possible address locations with a byte, when you graduate to devices larger than 256 bytes, you need two address. So for a DS2430 (256 bit), one TA. For a DS1972 (1024 bit), two TAs.
E/S is a status byte. Check your local datasheet. See, for example: https://datasheets.maximintegrated.com/en/ds/DS1972.pdf Colin On Thu, Oct 29, 2015 at 12:36 PM, Ritchie <rot...@gmx.de> wrote: > Hi to all, > > in which Module of the OWFS Server do I have to take a closer look > in matter of the Read/Write/Copy Scratch Pad function. > > How is the meaning of TA1/TA2 for these commands? > > TA1 = Start-Offset of the Bit 0...3 (masked) > TA2 = End-Offset of the Bit 0...3 (masked) > > I did not get the meaning of E/S Authorization Code 100%.
