Possible limitations on PLL input frequencies and multiplier factors should be checked before using the PMC.
Warning: Bit 29 must always be set to 1 when programming the CKGR_PLLR register.
This register can only be written if the WPEN bit is cleared in
• DIV: Divider
• PLLCOUNT: PLL Counter
Specifies the number of Slow Clock cycles x8 before the LOCK bit is set in PMC_SR after CKGR_PLLR is written.
• MUL: PLL Multiplier
0 = The PLL is deactivated.
1 up to 2047 = The PLL Clock frequency is the PLL input frequency multiplied by MUL + 1.
