Revision Description
13442.2549 ■ Marked LM3S5956 device as not recommended for new designs (NRND). Device is in production
to support existing customers, but TI does not recommend using this part in a new design.
■ Clarified that all GPIO signals are 5-V tolerant when configured as inputs except for PB0 and PB1,
which are limited to 3.6 V.
■ In the Watchdog Timers chapter, added information on servicing the watchdog timer to the
Initialization and Configuration section.
■ In the General-Purpose Timers chapter, added note to the GPTMTnV registers that in 16-bit mode,
only the lower 16-bits of the register can be written with a new value. Writes to the prescaler bits
have no effect.
■ Corrected reset for the UART Raw Interrupt Status (UARTRIS) register.
■ In the USB chapter, clarified that the USB PHY has internal termination resistors, and thus there is
no need for external resistors.
■ In the Electrical Characteristics chapter, added clarifying footnote to the GPIO Module Characteristics
table.
■ Additional minor data sheet clarifications and corrections.

■ 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.
