I have a question about axes signaturebytes and ram addresses?

for example I know that on this ecu the rpm axis is signed 3B, the manifold pressure is 43, water temperature is 3A ...

and sometimes in assembly code there are ram addresses that carry the same values:

mov MD1, B ; Multiplication/Division Register 1

mov MD4, RAM_43 ; Multiplication/Division Register 4

mov MD5, #0 ; Multiplication/Division Register 5

mov B, A ; B-Register

mov A, RAM_3B

cjne A, B, code_4FAA ; B-Register

Is there a relationship?
