*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. **
