Why this PBP code will blink PortB LED's but not the one on PortC?

When using I2CREAD/WRITE the PIC is "in control" of the line, ie it supplies the clock and is therfor the master (same as with SHIFTIN/OUT). Because of this IC2READ/WRITE won't work for a slave type device, however the MSSP module setup in I2C mode will, you just have to "drive it manually".

Thanks henrik, just in time to fix what I was doing. I think I did some bit banging slave stuff a few (>5) years ago in ASM, no desire to repeat that!! Off to make sure chip selection supports slave mode I2C.
