Examples:
Reads a byte over the I2C interface. In master mode this function will
generate the clock and in slave mode it will wait for the clock. There is no
timeout for the slave, use i2c_poll() to prevent a lockup. Use restart_wdt() in
the #USE I2C to strobe the watch-dog timer in the slave mode while waiting.
All devices.
#USE I2C
i2c_start();
i2c_write(0xa1);
data1 = i2c_read(TRUE);
data2 = i2c_read(FALSE);
i2c_stop();
