Load and Transfer Instructions 9.3 L STW Load Status Word into ACCU 1 Format Description Status word Example L STW L STW (instruction L with the address STW) loads ACCU 1 with the contents of the status word. The instruction is executed without regard to, and without affecting, the status bits. Note For the S7-300 series CPUs, the statement L STW does not load the FC, STA, and OR bits of the status word. Only bits 1, 4, 5, 6, 7, and 8 are loaded into the corresponding bit positions of the low word of accumulator 1.
