CP2114-EK

The CP2114 EVB ships with three default configurations in OTP at the following indices:

Index 0: Audio out and audio in streams both set to Asynchronous with CS42L55 DAC settings.

Index 1: Audio out and audio in streams both set to Asynchronous with WM8523 DAC settings.

Index 2: Audio out and audio in streams both set to Asynchronous with PCM1774 DAC settings.

The CurrentBootConfig parameter with a value of 0xFF indicates the CP2114 will not configure any DAC devices

on a reset or boot.This occurs when

DAC select input feature is turned on and no jumpers are installed on GPIO.5, GPIO.6, GPIO.7, and

GPIO.8.

DAC select input feature is turned on and the GPIO value is set to “Use OTP Boot Config” while no valid

boot config entry is found in the one-time programmable memory.

DAC select input feature is turned off and there is no valid Boot Config entry in the one-time programmable

memory.

The CP2114 has 32 programmable boot configuration entries by default. (The CP2114 boot configuration can be

changed up to a total of 32 times.)

The final parameter, AvailableOtPConfigSpace: 0x1532 indicates there are 0x1532 (5426) bytes of

programmable memory available to support new configurations.

4.1.2. Reset Device

This button forces a CP2114 reset.

4.1.3. Load Config Text from File

Loads configuration text from a file into the Config Text window.

4.1.4. Save Config Text to File

Saves the text in the Config Text window to a file.

4.1.5. Write Config Text to RAM

Writes the configuration displayed in the Config Text window into the CP2114 RAM. The DAC configurations are

also written to the DAC. This operation will cause the CP2114 to disconnect and reconnect on the USB bus. This

configuration is not retained on device reset.

4.1.6. Write Config Text to OTP

Writes the configuration in the Config Text window to the one-time programmable memory. The configuration does

not become the active configuration in RAM unless it’s specified in CP2114 Boot Config or via DAC select GPIO

pins followed by power cycling or resetting the device.

4.1.7. Read CP2114 Config from OTP

After specifying the configuration number in the text box to the right of the button and clicking the button, the utility

will display the one-time programmable memory configuration in the output window.

4.1.8. Set CP2114 Boot Config

After specifying the configuration number in the text box to the right of the button and clicking the button, the boot

configuration index is programmed into the one-time programmable memory space.

Note: The CP2114 boot configuration index can be changed up to 32 times.

4.1.9. Get DAC Registers

Displays one or more DAC registers in the output window. To display a contiguous range of DAC registers enter the

starting register address in the Start Address field and the number of registers to read in the Num Registers field.

Click Get DAC Registers and the register values will be displayed in the status window as hex comma-separated

values.

4.1.10. Save Final Device Customization to File

Save the final 5.5 kB of customized data into a file for one-time programming in production.
