Description
■ 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.
■ 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.

■ Reorganized ARM Cortex-M3 Processor Core, Memory Map and Interrupts chapters, creating two
new chapters, The Cortex-M3 Processor and Cortex-M3 Peripherals. Much additional content was
added, including all the Cortex-M3 registers.
■ Changed register names to be consistent with StellarisWare^® names: the Cortex-M3 Interrupt
Control and Status (ICSR) register to the Interrupt Control and State (INTCTRL) register, and
the Cortex-M3 Interrupt Set Enable (SETNA) register to the Interrupt 0-31 Set Enable (EN0)
register.
■ In the Internal Memory chapter:
– Added clarification of instruction execution during Flash operations.
– Deleted ROM Version (RMVER) register as it is not used.
■ In the GPIO chapter:
– Renamed the GPIO High-Speed Control (GPIOHSCTL) register to the GPIO High-Performance
Bus Control (GPIOHBCTL) register.
– Added clarification about the operation of the Advanced High-Performance Bus (AHB) and the
legacy Advanced Peripheral Bus (APB).
– Modified Figure 9-1 on page 353 and Figure 9-2 on page 354 to clarify operation of the GPIO
inputs when used as an alternate function.
■ In General-Purpose Timers chapter, clarified operation of the 32-bit RTC mode.
■ Numerous improvements and clarifications to the USB chapter. Also corrected definitions for bits
2 and 5 in the USBIE register.
■ In Electrical Characteristics chapter:
– Added "Input voltage for a GPIO configured as an analog input" value to Table 21-1 on page 775.
– Added I_LKG parameter (GPIO input leakage current) to Table 21-4 on page 776.
– Corrected values for t_CLKRF parameter (SSIClk rise/fall time) in Table 21-22 on page 786.
■ Added dimensions for Tray and Tape and Reel shipping mediums.
