Two dedicated clock resources for CapSense: SYSTEM RESOURCES Errata: For information on silicon errata, see Errata on page 35. Details include trigger conditions, devices affected, and proposed workaround. Note 1. Errata: When the device is operated within 0 C to 70 C, the frequency tolerance is reduced to 2.5%, but if operated at extreme temperature (below 0 C or above 70 C), frequency tolerance deviates from 2.5% to 5%. For more information, see Errata on page 35.
