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 USB chapter:
– Clarified that when the USB module is in operation, MOSC must be provided with a clock source,
and the system clock must be at least 30 MHz.
– Removed MULTTRAN bit from USB Transmit Hub Address Endpoint n (USBTXHUBADDRn)
and USB Receive Hub Address Endpoint n (USBRXHUBADDRn) registers.
– Corrected description for the USB Device RESUME Interrupt Mask (USBDRIM) register.
■ In Analog Comparators chapter, clarified internal reference programming.
■ In PWM chapter, clarified PWM Interrupt Enable (PWMINTEN) register description.
■ 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.
