Revision Description
9538 ■ Clarified "Reset Control" section in the "System Control" chapter.
■ Corrected USB PLL speed in "Main Clock Tree" diagram.
■ Clarified Hibernation module initialization and configuration.
■ Corrected reset value for DMA Channel Wait-on-Request Status (DMAWAITSTAT) register.
■ Corrected "GPIO Pins With Non-Zero Reset Values" table.
■ Clarified that that the timer reload only happens in periodic mode.
■ Clarified that only bit 0 in the Watchdog Control (WDTCTL) register is protected from writes once
set.
■ Added "Sample Averaging Example" diagram to ADC chapter.
■ Corrected "SSI Timing for SPI Frame Format" figure.
■ In "Electrical Characteristics" chapter:
– Deleted T_PORMIN parameter from "Power Characteristics" table, and deleted corresponding
diagram.
– Added t_ADCSAMP sample time parameter to "ADC Characteristics" table.
■ Additional minor data sheet clarifications and corrections.

■ Clarified Main Oscillator verification circuit sequence.
■ Added note that 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 reset of Device Mode (DEVMOD) bitfield in USB General-Purpose Control and Status
(USBGPCS) register.
■ Clarified initialization and configuration procedure in "Analog Comparators" chapter.
■ In Electrical Characteristics chapter:
– Added specification for maximum input voltage on a non-power pin when the microcontroller is
unpowered (V_NON parameter in Maximum Ratings table).
– Replaced Preliminary Current Consumption Specifications with Nominal Power Consumption,
Maximum Current Specifications, and Typical Current Consumption vs. Frequency sections.
– Clarified Reset, and Power and Brown-out Characteristics and added a new specification for
powering down before powering back up.
– Added characteristics required when using an external regulator to provide power for V_DDC.
■ Additional minor data sheet clarifications and corrections.
