![]() ![]() This is for future designs as my current stuff is already set in stone (so to speak). The only question is whether the ≈4MHz clock source from the SNES can pass through that resistor.Īll this said, it looks like it might be possible to port the supercic to the 10f322, which is a 6-pin part, and all four non-power pins from the PIC would necessarily then be brought to the cartridge edge. (I'd go up by an order of magnitude for safety's sake). ![]() The '629 is rated to a maximum of 20mA of clamp current, so any resistor strictly greater than (12V-5V)÷(20mA)=350Ω should keep it from dying. ![]() I guess it's possible you might be able to use a resistor to protect CLKIN while /MCLR is at +12V. Since the pin is already used as a "/PAIRING" input, /MCLR is probably already disabled the only question is whether the program would be confused by having that pin toggle continuously. Code: Select all REGISTER 9-1: CONFIG - CONFIGURATION WORD (ADDRESS: 2007h) ![]()
