Query Registers; Register 0X30 Get_Device_Param - SIGNALCORE SC5312A User Manual

Query Registers

These are request for data registers, in that a request for certain data is made by writing to the specific
register first, followed by reading back the requested data. Some registers may require instruction data to
specify the type of data to return, while others do not need any. For example, the register
GET_DEVICE_PARAM (0x30) returns the RF Frequency, IF1 Frequency, IF3 Frequency, etc.; the data
returned depends on the parameter value of the instruction byte.
Returned data length is always 8 bytes (64 bits), with the first byte being the most significant (MSB). It is
important that all 8 bytes are read to clear the interface buffers. How the different interface buses handle
the return data is explained in the Device Information Parameters and Format section.
