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?
maybe this will help you. remember, when you see all the code like mov MD1, B its read backwards from right to left. move B to MD1.
mov MD1, B ; This one is moving whatever is in register B to MD1
mov MD4, RAM_43 ; This one moces RAM_43 to MD4
mov MD5, #0 ; This one moves the HEX value 0 to MD5
mov B, A ; Move register A to register B
mov A, RAM_3B ; Move RAM_3B to register A
cjne A, B, code_4FAA ; Compare register B to A and jump if not equal.
