pll_init
void pll_init(PLL pll, uint ref_div, uint vco_freq, uint post_div1, uint post_div2)
Initialise specified PLL.
Definition: pll.c:13
pll_deinit
void pll_deinit(PLL pll)
Release/uninitialise specified PLL.This will turn off the power to the specified PLL. Note this function does not currently check if the PLL is in use before powering it off so should be used with care.
