Revision Description
11003 ■ Re-organized Architectural Overview chapter.
■ In the System Control chapter:
– Corrected reset value for Run Mode Clock Gating Control Register 0 (RCGC0) register.
– Corrected reset for the System Properties (SYSPROP) register.
– Removed TPSW bit from Non-Volatile Memory Information (NVMSTAT) register as the ROM
Software Map (ROMSWMAP) register contains this information.
■ Changed bit names in System Exception Raw Interrupt Status (SYSEXCRIS), System Exception
Interrupt Mask (SYSEXCIM), System Exception Masked Interrupt Status (SYSEXCMIS), and
System Exception Interrupt Clear (SYSEXCIC) registers to indicate they are for floating-point
exceptions.
■ In Hibernation chapter, added section "Arbitrary Power Removal" and corrected figure "Using a
Dedicated Oscillator as the Hibernation Clock Source with VDD3ON Mode ".
■ In the Internal Memory chapter, clarified programming and use of the non-volatile registers, including
corrections to the Boot Configuration (BOOTCFG) and User Register n (USER_REGn) registers.
■ In the GPIO chapter, corrected table "GPIO Pins With Non-Zero Reset Values".
■ In the General-Purpose Timers chapter, added clarifications on timer operation.
■ In the UART chapter, clarified interrupt behavior.
■ In the I²C chapter:
– Added content for Fast-Mode Plus (1 Mbps) mode and High-Speed mode (3.33 Mbps), correcting
the reset value of the Device Capabilities 2 (DC2), I²C Master Control/Status (I2CMCS), and
I²C Peripheral Properties (I2CPP) registers.
– Corrected reset for the I²C Master Control/Status (I2CMCS) register.
– Added the HSTPR bit to the I²C Master Timer Period (I2CMTPR) register.
– Added the I²C Peripheral Configuration (I2CPC) register.
■ In the USB chapter:
– Corrected description for the USB Device RESUME Interrupt Mask (USBDRIM) register.
■ In the Analog Comparators chapter:
– Corrected table "Internal Reference Voltage and ACREFCTL Field Values".
– Corrected bit fields in the Analog Comparator Peripheral Properties (ACMPPP) register.
■ In the Electrical Characteristics chapter:
– Clarified load capacitance equations.
– Corrected values in table "Analog Comparator Voltage Reference Characteristics".
■ Additional minor data sheet clarifications and corrections.
