0,drbcopy,lowbit instruction which tests the zero bit of the drbcopy register
to see if it is a “1” or a “0”. If it is a “1” then it will jump to the label referred to as
lowbit, otherwise it will not jump and the next instruction will be executed, but
since the zero bit of the drbcopy register is a “1” it will jump to the lowbit label.

Results: Look at the oscilloscope which is displaying the voltage level of pin
PB0 and note that it is high (5 V). The voltage level of PB0 is 5 V because PB0
is configured as Output Push-Pull with a “1” in its data register (DRB).

Results: Look at the oscilloscope which is displaying the voltage level of pin

If we carry on clicking the Cont button and stepping through the code we can
see that PB0 changes from a logic “0” (low - 0 V) to a logic “1” (high - 5 V) and
vice-versa. But, instead of doing that we will stop “Stepping” through the code
and “Run” through it instead.
