Revision Description
11108 ■ Added module-specific pin tables to each chapter in the new Signal Description sections.
■ In Hibernation chapter:
– Changed terminology from non-volatile memory to battery-backed memory.
– Clarified Hibernation module register reset conditions.
■ In Timer chapter, clarified that in 16-Bit Input Edge Time Mode, the timer is capable of capturing
three types of events: rising edge, falling edge, or both.
■ In UART chapter, clarified interrupt behavior.
■ In SSI chapter, corrected SSIClk in the figure "Synchronous Serial Frame Format (Single Transfer)".
■ In Signal Tables chapter:
– Corrected pin numbers in table "Connections for Unused Signals" (other pin tables were correct).
– Corrected buffer type for PWMn signals in pin tables.
■ In Electrical Characteristics chapter:
– Added parameter "Input voltage for a GPIO configured as an analog input" to the "Maximum
Ratings" table.
– Corrected Nom values for parameters "TCK clock Low time" and "TCK clock High time" in "JTAG
Characteristics" table.
– Corrected missing values for "Conversion time" and "Conversion rate" parameters in "ADC
Characteristics" table.
■ Additional minor data sheet clarifications and corrections.

■ In Application Interrupt and Reset Control (APINT) register, changed bit name from SYSRESETREQ
to SYSRESREQ.
■ Added DEBUG (Debug Priority) bit field to System Handler Priority 3 (SYSPRI3) register.
■ Added "Reset Sources" table to System Control chapter.
■ Removed mention of false-start bit detection in the UART chapter. This feature is not supported.
■ Added note that specific module clocks must be enabled before that module's registers can be
programmed. There must be a delay of 3 system clocks after the module clock is enabled before
any of that module's registers are accessed.
■ Changed I²C slave register base addresses and offsets to be relative to the I²C module base address
of 0x4002.0000 and 0x4002.1000, so register bases and offsets were changed for all I²C slave
registers. Note that the hw_i2c.h file in the StellarisWare^® Driver Library uses a base address of
0x4002.0800 and 0x4002.1800 for the I²C slave registers. Be aware when using registers with
offsets between 0x800 and 0x818 that StellarisWare uses the old slave base address for these
offsets.
■ Added GNDPHY and VCCPHY to Connections for Unused Signals tables.
■ Corrected nonlinearity and offset error parameters (E_L, E_D and E_O) in ADC Characteristics table.
■ Added specification for maximum input voltage on a non-power pin when the microcontroller is
unpowered (V_NON parameter in Maximum Ratings table).
■ Additional minor data sheet clarifications and corrections.
