8-Bit CMOS Microcontrollers

Microchip Technology 

PIC16C6X

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 enable 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.

Legend: x = unknown, - = unimplemented locations read as '0'. Shaded cells are not used for Asynchronous Reception.

Note 1: PSPIE and PSPIF are reserved on the PIC16C63/R63/66, always maintain these bits clear.

2: PIE1<6> and PIR1<6> are reserved, always maintain these bits clear.
