• OFF in all other cases.
SETA
SETA(530) turns ON 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.)
Bits turned ON by SETA(530) can be
turned OFF by any other instructions, not
just RSTA(531).
