clarification on I/O ops

hi @dr-orlovsky, I have some questions on I/O operations

https://github.com/pandoracore/alure/blob/3a98a1f85699409333040f0c93775e96e8d3eb00/src/isa.rs#L12

I could not find docs on AluReOp and I am assuming like this: Read and Store is for input, and Check and Load is for output. So read on assembly would be split into 2 operations, which are Read and Store. thus

read a16[2], $cycle_limit

would be converted to

Read(<some u16 value representing internal ID for $cycle_limit>)
StoreA(RegA::A16, Reg16::Reg2, u8)

In this scenario, however, I am not sure what is 3rd argument u8 for. Could you tell me brief explanations on these ops?

Unlike RegA, RegR and RegF, RegS is internally u4 which stands for register index. So specifying index in 2nd argument Reg16 would not make sense.
