Executes the primitive block transfer instruction in the continued
byte while CW
≠
0, and decrements CW by one. If any interruption
is held at this time, it is processed. The program exits the loop
when CY

Executes the primitive block transfer instruction in the continued
byte while CW
≠
0, and decrements CW by one. If any interruption
is held at this time, it is processed. The program exits the loop
when the primitive block transfer instruction is CMPBK or CMPM,
and when Z
≠
1.
Same as above.
The program exits the loop when Z
≠
0.
