Sequence Output Instructions Section 3-3
Bits turned ON by SETA(530) can be turned OFF by any other instructions,
not just RSTA(531).
SETA(530) can be used to turn ON bits in data areas that are normally
accessed by words only, such as the DM area.
Operation of RSTA(531)
RSTA(531) turns OFF N2 bits, beginning from bit N1 of D, and continuing to
the left (more-significant bits). All other bits are left unchanged. (No changes
will be made if N2 is set to 0.)
