What does line tagged with 0 and 1 mean in DineroIV trace output?

[ombadei]

I was given the below trace output (only showing the beginning section) from dineroIV cache simulator. The actual trace is roughly 70 over million lines and sized at 500MB.

While i can presume that the lines tagged with '2' belongs to an instruction not dealing with main memory, i am not sure whether '0' and '1' means read and write to memory or vice versa. Does anyone know?
