Revision Description
9970 ■ Corrected "Reset Sources" table.
■ Added missing PICAL (PIOSC Calibrate) bit to DC4 register.
■ Added Important Note that RCC register must be written before RCC2 register.
■ Added a note that all GPIO signals are 5-V tolerant when configured as inputs except for PB0 and
PB1, which are limited to 3.6 V.
■ Note that the state of the HSE bit in the UARTCTL register has no effect on clock generation in ISO
7816 smart card mode (when the SMART bit in the UARTCTL register is set).
■ Corrected LIN Mode bit names in UART Interrupt Clear (UARTICR) register.
■ Corrected pin number for RST in table "Connections for Unused Signals" (other pin tables were
correct).
■ In the "Operating Characteristics" chapter:
– In the "Thermal Characteristics" table, the Thermal resistance value was changed.
– In the "ESD Absolute Maximum Ratings" table, the V_ESDCDM parameter was changed and the
V_ESDMM parameter was deleted.
■ The "Electrical Characteristics" chapter was reorganized by module. In addition, some of the
Recommended DC Operating Conditions, LDO Regulator, Clock, GPIO, EPI, Hibernation Module,
ADC, and SSI characteristics were finalized.
■ Added missing ordering table.
■ Additional minor data sheet clarifications and corrections.
