bit_set(PIE1,0);
where PIE1 is the register where PIE1 is located on your PIC. |

Further answers:
#byte PIE1=(put address here to suit the chip concerned)
#bit PIE1BIT0=PIE1.0
Then PIE1BIT0=1 will set it, and PIE1BIT0=0 will clear it.
Or, since PIE1.0, is normally the 'timer1 interrupt enable' bit, use the inbuilt instruction:
enable_interrupts(INT_TIMER1);
The latter has the advantage of remaining portable, if you change to another chip (16 to 18 for example). In general, I'd recommend this.

Hi I tried this:
| Code: |
#BYTE RCSTA=0x18;
#BIT RCSTABIT7=RCSTA.7;
|
But I am given an "Expecting a declaration" error message.
What is my mistake? |
