DPLLSTAT
1
Status bit indicating if the DPLL is the source for the USB module clock.
DPLLSTAT = 0
DPLLSTAT = 1
Status bit indicating if the APLL is the source for the USB module clock.
The DPLL is not the USB module clock source.
The DPLL is the USB module clock source.

MULT
0
PLL Multiply Factor K. Multiply Factor K, combined with DIV and MODE, determines the final PLL output
clock frequency.
K = MULT[3:0] + 1
11
DIV
0
PLL Divide Factor (D) selection bit for PLL multiply mode operation. DIV, combined with K and MODE,
determines the final PLL output clock frequency. When the PLL is operating in multiply mode:
DIV = 0
DIV = 1
PLL Divide Factor D = 1
PLL Divide Factor D = 2 if K is odd
PLL Divide Factor D = 4 if K is even
103
COUNT
0
8-bit counter for PLL lock timer. When the MODE bit is set to 1, the COUNT field starts decrementing by 1
at the rate of CLKIN/16. When COUNT decrements to 0, the STAT bit is set to 1 and the PLL enabled clock
is sourced to the USB module.
