\n * Setting the phase of a clock requires that you manually set the PLL and<\/span>
\n * take the PLL frequency into account when calculation the value to place<\/span>
\n * in the phase register. As shown on page 10 of Silicon Labs Application<\/span>
\n * Note 619 (AN619), the phase register is a 7-bit register, where a bit<\/span>
\n * represents a phase difference of 1\/4 the PLL period. Therefore, the best<\/span>
\n * way to get an accurate phase setting is to make the PLL an even multiple<\/span>
\n * of the clock frequency, depending on what phase you need.<\/span>
\n *<\/span>
\n * If you need a 90 degree phase shift (as in many RF applications), then<\/span>
\n * it is quite easy to determine your parameters. Pick a PLL frequency that<\/span>
\n * is an even multiple of your clock frequency (remember that the PLL needs<\/span>
\n * to be in the range of 600 to 900 MHz). Then to set a 90 degree phase shift,<\/span>
\n * you simply enter that multiple into the phase register. Remember when <\/span>
\n * setting multiple outputs to be phase-related to each other, they each need<\/span>
\n * to be referenced to the same PLL.<\/span>
