Notes:
1. Rise and fall times for the SYSCLK input are measured from 0.4 V to 2.4 V.
2. Cycle-to-cycle jitter is guaranteed by design.
3. Timing is guaranteed by design and characterization, and is not tested.
4. PLL relock time is the maximum amount of time required for PLL lock after a stable Vdd, OVdd, AVdd and SYSCLK are reached during the
power-onreset sequence. This specification also applies when the PLL has been disabled and subsequently re-enabled during sleep mode.
Also note that HRESET must be held asserted for a minimum of 255 bus clocks after the PLL relock time (100
ms) during the power-on reset
sequence.
5. Caution: The SYSCLK frequency and PLL_CFG[0–3] settings must be chosen such that the resulting SYSCLK (bus) frequency, CPU (core)
frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating frequencies. Refer to the PLL_CFG[0–3]
signal description for valid PLL_CFG[0–3] settings.
