Revision Description
11425 ■ In System Control chapter:
– Clarified that an external LDO cannot be used.
– Clarified system clock requirements when the ADC module is in operation.
– Added important note to write the RCC register before the RCC2 register.
■ In Hibernation chapter:
– Changed terminology from non-volatile memory to battery-backed memory.
– Numerous clarifications, including adding a section "System Implementation".
– Clarified Hibernation module register reset conditions.
■ In Internal Memory chapter, clarified programming and use of the non-volatile registers.
■ In GPIO chapter, corrected "GPIO Pins With Non-Zero Reset Values" table and added note that if
the same signal is assigned to two different GPIO port pins, the signal is assigned to the port with
the lowest letter.
■ In Timer chapter, clarified timer modes and interrupts.
■ In ADC chapter, added "ADC Input Equivalency Diagram".
■ In UART chapter, clarified interrupt behavior.
■ In SSI chapter, corrected SSIClk in the figure "Synchronous Serial Frame Format (Single Transfer)"
and clarified behavior of transmit bits in interrupt registers.
■ In I²C chapter, corrected bit and register reset values for IDLE bit in I²C Master Control/Status
(I2CMCS) register.
■ In Analog Comparators chapter, clarified internal reference programming.
■ In Signal Tables chapter, clarified VDDC and LDO pin descriptions.
■ In Electrical Characteristics chapter:
– In Maximum Ratings table, deleted parameter "Input voltage for a GPIO configured as an analog
input".
– In Recommended DC Operating Conditions table, corrected values for I_OH parameter.
– In Load Conditions figure, corrected value for C_L parameter.
– In JTAG Characteristics, table, corrected values for parameters "TCK clock Low time" and "TCK
clock High time".
– In LDO Regulator Characteristics table, added clarifying footnote to C_LDO parameter.
– In System Clock Characteristics with ADC Operation table, added clarifying footnote to F_sysadc
parameter.
– In Sleep Modes AC Characteristics table, split parameter "Time to wake from interrupt" into
sleep mode and deep-sleep mode parameters.
