Stop bit
WriteI2C2
Status byte for WCOL detection.
Single data byte for I2C2 bus.
This routine writes a single byte to the
I2C2 bus.
//Stop condition
//Wait for flag to set
// write single byte to SSP2BUF
// test if write collision occurred
// wait until write cycle is complete
// if WCOL bit is set return negative #
// if WCOL bit is not set return non-negative #
