Preliminary

Storing Custom Configurations

The application comes pre-configured with a few useful paths that can be found in the Paths

menu.

To add new paths, simply set up the desired configuration and select ‘Add Path’ from the Paths

menu, a window will appear asking for a name for this configuration. Fill in a descriptive name

(max 32 characters) and click OK to store this path. The paths are permanently stored on the

computer. A maximum of 32 paths can be stored.

To remove a stored path, select the path from the Path menu and click ‘Remove Path’ in the Path

menu. The Path will be permanently removed.

Analog Play and Record

The ES521 Demo System allows full playback and record capabilities from the main application

window. The 5216 supports two types of addressing:

Use current address – Recording or Playback starts from the position of the current address

pointer, no address is sent as part of the command. The address pointer can be retrieved from by

pressing the ‘Read Status’ button which displays the address bytes as two hexadecimal numbers

(high and low address byte)

Supply address – Record and Playback can be setup by sending an address with the Play or

Record command. See the 5216 datasheet for addressing details.

Play – Play from the current address

Play from address – Play from the address given in the box below the button.

Record – Record from the current address.

Record from address – Record from the address given in the box below the button.

The Status Register

The Status register gives an indication of what the chip is currently doing, and the current address

pointer.

Select which chip to use (main or secondary 5216) and click the ‘Read Status’ button near the

bottom of the screen to update the status. It gives the following information:
