Hello all;

I am using LPC2148.I have write code like this.e.g.
     switch ( s )
      {
      case 0x00:
          IO0SET |= (1<<1);
          IO0CLR |= (1<<2);
          IO0SET |= (1<<3);
          IO0SET |= (1<<4);
          break; }
I want to assign port pin directly through bit(like used in 8051 sbit)
Have you any suggestion?

I am using SCARM compilar.

As far as I know there are no instuctions in this controller-family that
can be compared to MC51's sbit for an IO-Pin. The GPIO-Module is
accessed through 32bit registers. But you should re-read the manual: |=
is not needed. For "higher speed" enable FIO and use the FIO registers
instead of "legacy" IO

Whatever this is.

Thanks alot.
