#85704 - differences Responding to: ???'s previous message |
Are there any electrical difference between them ?
Most likely, on some parametres one will be to the low side, the other to the high side. If your product is "tested" instead of "designed" all bets are off. This is by a wide margin, the most common reason that "equivalents" do not "work". Could the new SPI functions ( P1.5; P1.6;P1.7;P1.8) introduce any bug ? If this has changed any of the pins to open collector (as the IIC pins), then yes, otherwise no. This, of course exclude the possibility that you have a "wild write" to a SFR that dis not exist on the RD2. http://www.hacon.com.br/arquivos/checkbox is a dead link Erik |
