When setting up an Asynchronous Reception with
address detect enabled:
• Initialize the SPBRG register for the appropriate
• Enable the asynchronous serial port by clearing
• If interrupts are desired, then set enable bit RCIE.
• Set bit RX9 to enable 9-bit reception.
• Set ADDEN to enable address detect.
• Enable the reception by setting enable bit CREN.
