Effects of positive transitions on the Sequence Event Register:
Sequence event
Layer 1
Layer 2
A) Positive Transition (PTR) Register
B) Negative Transition (NTR) Register

Line 10 Sets Bits B1 and B10 of the PTR Operation Transition Filter, and then queries the
register.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the decimal value that defines which bits in the register are set (1026).

Sets B1 when in arm layer 1.
Sets B2 when in arm layer 2.
