CONFIGURATION OF THE ICE USING WISCE™
The WM832x devices can only read the ICE contents though WISCE™ (Wolfson Interactive Setup
and Configuration Environment) by selecting the appropriate WMDBxx device description to program
the EEPROM.
The configuration procedure is as below:
1.
Open WISCE™ (download WISCE™ software from the Wolfson website:
http://www.wolfsonmicro.com/support/wisce/
)
2.
Load the WMDBxx device by clicking to ‘’Device’’ then ‘’Load Device’’.
3.
Select the desired register settings (register R02h to R1Eh, R00 can be disregarded) using the
slides and by clicking on the appropriate register bits.
4.
The DBE_VALID_DATA field (R2Eh register) should contain the value ‘’A596h’’ for the ICE data
to be deemed valid.
5.
Finally, ‘’Write’’ each register values to program the ICE.
After the desired register settings are loaded into the ICE, the same block of data will be mirrored in
the main Register Map of the WM832x. Data from the external ICE can be loaded into the Window
area in the main Register Map as below (R7810h to R7827h).
The R7810h to R7827 registers contain the bootstrap configuration data. This defines the sequence
and voltage requirements for powering up the WM832x and for configuring functions such as the
clocks, GPIOs and LED status indicators. Under default conditions, the bootstrap data is loaded into
the Window when the WM832x schedules an ‘On’ transition.
For detailed information on the functionality and ICE connections, please see the WM832x
datasheets.
