System Resets Ref. Pump Pull-up, pull-down, high Z, strong, or open-drain drive modes SYSTEM RESOURCES on all GPIOs Eight standard analog inputs on GPIOs, plus four additional analog inputs with restricted routing Errata: For information on silicon errata, see Errata on page 63. 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%.
