Revision Description
7783
■ 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.
■ Added clarification of instruction execution during Flash operations.
■ Modified Figure 7-2 on page 233 to clarify operation of the GPIO inputs when used as an alternate
function.
■ Added caution not to apply a Low value to PB7 when debugging; a Low value on the pin causes
the JTAG controller to be reset, resulting in a loss of JTAG communication.
■ In General-Purpose Timers chapter, clarified operation of the 32-bit RTC mode.
■ Added missing table "Connections for Unused Signals" (Table 17-5 on page 522).
■ In Electrical Characteristics chapter:
– Added I_LKG parameter (GPIO input leakage current) to Table 19-4 on page 525.
– Corrected values for t_CLKRF parameter (SSIClk rise/fall time) in Table 19-16 on page 533.
■ Added dimensions for Tray and Tape and Reel shipping mediums.

■ Corrected base address for SRAM in architectural overview chapter.
■ Clarified system clock operation, adding content to “Clock Control” on page 158.
■ In Signal Tables chapter, added table "Connections for Unused Signals."
■ In "Reset Characteristics" table, corrected value for supply voltage (VDD) rise time.
■ Additional minor data sheet clarifications and corrections.

■ Added caution note to the I²C Master Timer Period (I2CMTPR) register description and changed
field width to 7 bits.
■ Added note about RST signal routing.
■ Clarified the function of the TnSTALL bit in the GPTMCTL register.
■ Additional minor data sheet clarifications and corrections.
