• Bit 7– PINMUX: PLL Input Multiplexer
This bit selects the clock input of the PLL:
• Bit 6– PLLUSB: PLL Postcaler for USB Peripheral
This bit select the division factor between the PLL output frequency and the USB module input
frequency:
• Bit 5..4 – PLLTM1:0: PLL Postcaler for High Speed Timer
These bits codes for the division factor between the PLL Output Frequency and the High Speed
Timer input frequency.
Note that the division factor 1.5 will introduce some jitter in the clock, but keeping the error null
since the average duty cycle is 50%. See
Figure 6-7.
• Bit 3..0 – PDIV3:0 PLL Lock Frequency
These bits configure the PLL internal VCO clock reference according to the required output fre-
quency value.

– PINMUX = 0: the PLL input is connected to the PLL Prescaler, that has the Primary
– PINMUX = 1: the PLL input is directly connected to the Internal Calibrated 8MHz RC
– PLLUSB = 0: no division, direct connection (if PLL Output = 48 MHz)
– PLLUSB = 1: PLL Output frequency is divided by 2 and sent to USB module (if PLL
System Clock as source
Oscillator. This mode allows to work in USB Low Speed mode with no crystal or
using a crystal with a value different of 8/16MHz.
