OSC and PLL block
The OSC and PLL block on the F2810 and F2812 will use a zero-pin Phase-Locked Loop (ZPLL). Figure 10
shows the implemented features and relevant signals.

Figure 10. OSC and PLL Block
The OSC circuit enables a crystal to be attached to the F2810 and F2812 devices using the X1 and X2 pins.
If a crystal is not used, then an external oscillator can be directly connected to the XCLKIN pin and the X2 pin
is left unconnected. The oscillator input range is 20 MHz to 35 MHz.

These bits set the PLL clocking ratio. The range of values should be between
(x 1.0) to (x 10.0). The scale between these values should be as linear as
possible:

The PLLCR register is reset to a known state by the XRS reset line. If a reset is issued by the debugger, the PLL clocking ratio is not changed.
