8.6.4 USB and HRCAP PLL Module (PLL2)

In addition to the main system PLL, these devices also contain a second PLL (PLL2) which can be used to clock the USB and HRCAP peripherals. The PLL supports multipliers of 1 to 15 and has a fixed divide-by-two on its output.

PLL2 may be clocked from the following three sources by modifying the PLL2CLKSRCSEL bits appropriately in the PLL2CTL register:

  • INTOSC1 (Internal Zero-pin Oscillator 1): This is the on-chip internal oscillator 1 and provides a 10-MHz clock. If used as a clock source for HRCAP, the oscillator compensation routine should be called frequently. Because of accuracy requirements, INTOSC1 cannot be used as a clock source for the USB.
  • Crystal/Resonator Operation: The (crystal) oscillator enables the use of an external crystal or resonator attached to the device to provide the time base. The crystal or resonator is connected to the X1/X2 pins.
  • External Clock Source Operation: This mode allows the reference clock to be derived from an external single-ended clock source connected to either GPIO19 or GPIO38. The XCLKINSEL bit in the XCLK register should be set appropriately to enable the selected GPIO to drive XCLKIN.

Note:

For proper operation of the USB module, PLL2 should be configured to generate a 120-MHz clock. This will be divided by two to yield the desired 60 MHz for the USB peripheral.

HRCAP supports a maximum clock input frequency of 120 MHz.
