Don't worry about slowing down, any good C compiler will waste at most
one or to instruction cycles for each read. And you may use in-line
assembly if you like.

Plain asm (PIC12/16):
  movf RCREG,w

Plain asm (PIC18):
  movf RCREG,w,ACCESS

Plain 'C':
  dummy =3D RCREG;

In-line assembly (Hi-Tech PICC):
asm( "movf RCREG,w" );

In-line assembly (Hi-Tech PICC-18):
asm( "movf RCREG,w,ACCESS" );

In-line assembly (MPLAB-C18):
_asm movf RCREG,w,ACCESS _endasm
