82 / 160 page ![]() PIC16F62X DS40300B-page 82 Preliminary © 1999 Microchip Technology Inc. Steps to follow when setting up an Asynchronous Reception: 1. Initialize the SPBRG register for the appropriate baud rate. If a high speed baud rate is desired, set bit BRGH. (Section 12.1). 2. Enable the asynchronous serial port by clearing bit SYNC, and setting bit SPEN. 3. If interrupts are desired, then set enable bit RCIE. 4. If 9-bit reception is desired, then set bit RX9. 5. Enable the reception by setting bit CREN. 6. Flag bit RCIF will be set when reception is com- plete and an interrupt will be generated if enable bit RCIE was set. 7. Read the RCSTA register to get the ninth bit (if enabled) and determine if any error occurred during reception. 8. Read the 8-bit received data by reading the RCREG register. 9. If any error occurred, clear the error by clearing enable bit CREN.
