Function
SU RS N N Y 5.6 Set bit in system data area unconditionally.
RU RS N N Y 5.6 Reset bit in system data area unconditionally.
LIR N N N 170 Load the contents of a memory word (addressed by
ACCU 1) indirectly into the register (0: ACCU 1; 2:
ACCU 2).
TIR N N N 106 Transfer the register contents (0: ACCU 1; 2: ACCU 2)
indirectly into the memory word (addressed by ACCU 1).
TNB Parameter
n=0 to 255
