(1) Connect CVDD and CVCORE between VDD/VSS and VCORE/VSS, respectively, as close to the device pins as possible. A low-ESR capacitor with at least the specified value and tolerance of ±20% or better is required for CVDD and CVCORE.
(2) The VCORE pin must only be connected to CVCORE. Do not supply any voltage or apply any external load to the VCORE pin.
(3) Wait states are managed automatically by the system controller (SYSCTL) and do not need to be configured by application software unless MCLK is sourced from a high speed clock source (HSCLK sourced from HFCLK or SYSPLL).
