Bit B1, Sequence 1 (Seq1) — Set bit indicates that the instrument is in an arm layer (PTR), or
that the instrument has exited from the arm layers (NTR).
Bits B2 through B15 — Not used.
Sequence Event Register:
Bit B0 — Not used.
Bit B1, Layer 1 (Lay1) — Set bit indicates that instrument operation is in arm layer 1 (PTR),
or that operation has exited from arm layer 1 NTR).
Bit B2, Layer 2 (Lay2) — Set bit indicates that instrument operation is in arm layer 2 (PTR),
or that operation has exited from arm layer 2 NTR).
Bits B3 through B15 — Not used.
