Possible limitations on PLLB input frequencies and multiplier factors should be checked before using the PMC.
This register can only be written if the WPEN bit is cleared in
• DIVB: Divider
• PLLBCOUNT: PLLB Counter
Specifies the number of Slow Clock cycles x8 before the LOCKB bit is set in PMC_SR after CKGR_PLLBR is written.
• MULB: PLLB Multiplier
0 = The PLLB is deactivated.
1 up to 2047 = The PLLB Clock frequency is the PLLB input frequency multiplied by MULB + 1.
