I don't think I understand what's going on with the reset pin.
The datasheet http://ww1.microchip.com/downloa... talks about the POR resetting the chip to it's default state, which I understand, but it says nothing about what the reset pin does.
Does it work like the POR or simply resets any I/O pin set as output to zero? :roll: (I hope the later)
This would be similar to the MCP23x16 or MCP23x17 both the I2C version which I'm using or the SPI version.
Does anyboby have any ideas? It's Sunday and I'm trying to finish off some PCB artwork and my not-so-friendly?? (other company) FAE will not be in the office until tomorrow.
