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.
