Register Name:CKGR_PLLBR
Address:
Access Type:Read-write
Possible limitations on PLLB input frequencies and multiplier factors should be checked before using the PMC.
• DIVB Divider B
• PLLBCOUNT: PLL B Counter
Specifies the number of slow clock cycles before the LOCKB bit is set in PMC_SR after CKGR_PLLBR is written.
• OUTB: PLL B Clock Frequency Range
To optimize clock performance, this field must be programmed as specified in “PLL Characteristics” in the Electrical Char-
acteristics section of the product datasheet.
• MULB: PLL B Multiplier
0 = The PLL B is deactivated.
1 up to 2047 = The PLL B Clock frequency is the PLL B input frequency multiplied by MULB + 1.
• USBDIV: Divider for USB Clock
