FMPLL electrical characteristics

The device provides a frequency modulated phase locked loop (FMPLL) module to generate a fast system

clock from the main oscillator driver.

DD = 3.3 V ± 10% / 5.0 V ± 10%, TA = −40 to 125 °C, unless otherwise specified. Values are specified for no

neighbor GPIO pin activity. If oscillator is enabled (OSC32K_XTAL and OSC32K_EXTAL pins), neighboring pins

should not toggle.
