Operation:
1 if the result was 0, else Z will be cleared to 0. This instruction is useful for subtracting
the carry from the upper byte of a double-byte value after the lower byte has been
subtracted.

Subtract bit from fr
Cycles: 2
If bit reads 0, fr is decremented. If fr was decremented, Z will be set to
fr,1
Swap nibbles in fr
Cycles: 1
The high- and low-order nibbles in fr are swapped.
Test fr for zero
Cycles: 1
Fr is read and copied back to itself. Z will be set to 1 if the value moved
