... If coming out of the SHUTDOWN via SMBus, an SMBus “wake-up” byte is required. This byte is discarded, and normal SMBus communication can proceed after the power on reset (ipor) is asserted to the host.

... In OOK mode, any value except will result in Err 0x04 – bad parameter in ARG4. In FSK mode, the minimum data rate is 200 bps. The ramp rate parameter dictates the minimum data rate. The Si4012 will set Err to 0x10 (data rate not supported) if the value is smaller than the minimum data rate on the specified Ramp Rate. ...
