... W6810/W681310 Conversion to W681513 The W6810DK has to be modified to allow the demonstration of the W681513 because of the 2.000 MHz clock rather than the 2.048 MHz standard frequency. The W681xxx- DK board is designed to divide 2048 KHz by 256 to get the 8 KHz sample clock. For the W681513 we substitute a 4.000 MHz crystal on the board and then build an external divider to do the divide by 250 to get 8 KHz again ...
