Re: [OPEN] Bitmine CoinCraft 28nm chip distribution (December W50, 42.5BTC/THps)
I have a question about the RESP_BIT. It seems it's only used for the 0x08 command.
If MCU want to read the result from chip 15, MCU will send out 0x080F. The spec says the RESP bit is set to 1, so that means the return format shall be 0x18FFDATA but it also says JOB_ID is Y i.e. 0xY8NNDATA. However the Job ID can be from 1 to 4. So there is a conflict, how does it represent Job ID#2 ? If it send out 0x28NNDATA then the RESP bit is not set, if the RESP bit is set, it would be 0x38NNDATA.
Does this mean that the JOB ID occupies the upper two bits?
i.e.
Return format:
32'b aabb1000NNNNNNNNDATADATADATADATA
where aa = job ID, bb = resp bit
Please clarify
