*Note:		**

*DLOOP is a delay loop variable used in flash algorithms. ** *This is a function of CLKOUT1. If the F206 device runs at ** *any CLKOUT1 speed other than 20 MHz, DLOOP value should be **

*redefined per the equation explained below. Use of	**
*current DLOOP for flash programming at speeds other than	**
*20 MHz is not recommended.	**
