System PLL relock time
The SYS_XTAL frequency and PLL Configuration bits must be chosen such that the resulting system frequency,
CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating
frequencies.
This represents total input jitter - short term and long term combined - and is guaranteed by design. Two different
types of jitter can exist on the input to core_sysclk, systemic and true random jitter. True random jitter is rejected, but
the PLL. Systemic jitter will be passed into and through the PLL to the internal clock circuitry, directly reducing the
operating frequency.
Relock time is guaranteed by design and characterization. PLL-relock time is the maximum amount of time required
for the PLL lock after a stable Vdd and core_sysclk are reached during the power-on reset sequence. This
specification also applies when the PLL has been disabled and subsequently re-enabled during sleep modes.
The system PLL (SYS_PLL) takes an external reference frequency and generates the internal
system clock. The system clock frequency is determined by the external reference frequency and
the settings of the SYS_PLL configuration.
The G2_LE core PLL (CORE_PLL) generates a master clock for all of the CPU circuitry. The
G2_LE core clock frequency is determined by the system clock frequency and the settings of the
CORE_PLL configuration.
