Address
Initialize the SPBRG register for the appropriate
baud rate. If a high-speed baud rate is desired,
set bit BRGH (Section 11.1 “AUSART Baud
Rate Generator (BRG)”).
Enable the asynchronous serial port by clearing
bit SYNC and setting bit SPEN.
If interrupts are desired, then set enable bit
RCIE.
If 9-bit reception is desired, then set bit RX9.
Enable the reception by setting bit CREN.
x = unknown, - = unimplemented locations read as ‘0’. Shaded cells are not used for asynchronous reception.
This bit is only implemented on the PIC16F88. The bit will read ‘0’ on the PIC16F87.

Bit 2
Flag bit RCIF will be set when reception is com-
plete and an interrupt will be generated if enable
bit RCIE is set.
Read the RCSTA register to get the ninth bit (if
enabled) and determine if any error occurred
during reception.
Read the 8-bit received data by reading the
RCREG register.
If any error occurred, clear the error by clearing
enable bit CREN.
(bits 7 and 6) of the INTCON register are set.
