I2C0CR2<I2CM> to 1 to enable I
Programming example: Initializing the device
After ensuring that the I2C0DA and I2C0CL pins are high (bus free), set
Next, set I2C0CR1<ACK> to 1, I2C0CR1<NOACK> to 0 and I2C0CR1<BC> to 0y000.
Then, set the slave address in I2C0AR<SA> and set I2C0AR<ALS> to 0 to select the
Finally, set I2C0CR2<MST>, I2C0CR2<TRX> and I2C0CR2<BB> to 0, I2C0CR2<PIN>
generated by any device after all the devices connected to the bus have been initialized. If this constraint is
not observed, another device may start a transfer before the initiaization of I
may not be received properly.
