The Register Read/Write window allows you to read and write bytes of data from and to a DSP IC, for some DSPs it also performs program file loading and data capture.
To access the Register Control window:
This window allows you to read and write bytes of data directly to Parameter RAM, Program RAM, Target/Slew RAM, and available registers, which is useful for sending specific parameters directly to the DSP and also checking parameter values that have been sent.
Note: Only 28 bits of the 32 available are used, so the 4 MSBs of the first hex value are zero-padded from the 4th bit. (This is different from the Capture Output Data window and params file, which are sign-extended from the fourth bit.) It also is important to keep in mind that Register Read is actually reading parameters back from the DSP, whereas Capture Output Data and params file are reading the parameters being sent.
These functions allow any node in the signal-processing flow to be sent to control-port-readable registers or to a digital output pin, provided it's supported by your particular hardware settings. This can be used to monitor and display information about internal signal levels or compressor / limiter activity. The digital output registers are output on SDATA_OUT7 when the data-capture serial-out enable bit (bit 14) is set in serial output control register 2. (This is AD1940-specific). Clicking Enable DCS Out sets this bit for you.
These functions allow loading a previously compiled program or parameter file to the hardware, provided this feature is support by your particular DSP part. This can be used to quickly compare project settings.

File load functionality for the AD1940/AD1940 is available through the Imploader.
