Revision Description
6712 ■ In "System Control" section, clarified Debug Access Port operation after Sleep modes.
■ Clarified wording on Flash memory access errors.
■ Added section on Flash interrupts.
■ Changed the reset value of the ADC Sample Sequence Result FIFO n (ADCSSFIFOn) registers
to be indeterminate.
■ Clarified operation of SSI transmit FIFO.
■ Made these changes to the Operating Characteristics chapter:
– Added storage temperature ratings to "Temperature Characteristics" table
– Added "ESD Absolute Maximum Ratings" table
■ Made these changes to the Electrical Characteristics chapter:
– In "Flash Memory Characteristics" table, corrected Mass erase time
– Added sleep and deep-sleep wake-up times ("Sleep Modes AC Characteristics" table)
– In "Reset Characteristics" table, corrected units for supply voltage (VDD) rise time

■ Deleted MAXADCSPD bit field from DCGC0 register as it is not applicable in Deep-Sleep mode.
■ Removed erroneous reference to the WRC bit in the Hibernation chapter.
■ Deleted reset value for 16-bit mode from GPTMTAILR, GPTMTAMATCHR, and GPTMTAR registers
because the module resets in 32-bit mode.
■ Clarified PWM source for ADC triggering.
■ Made these changes to the Electrical Characteristics chapter:
– Removed V_SIH and V_SIL parameters from Operating Conditions table.
– Added table showing actual PLL frequency depending on input crystal.
– Changed the name of the t_{HIB_REG_WRITE} parameter to t_{HIB_REG_ACCESS}.
– Revised ADC electrical specifications to clarify, including reorganizing and adding new data.
– Changed SSI set up and hold times to be expressed in system clocks, not ns.

Corrected ordering numbers.
■ Clarified Power-on reset and RST pin operation; added new diagrams.
■ Corrected the reset value of the Hibernation Data (HIBDATA) and Hibernation Control (HIBCTL)
registers.
■ Clarified explanation of nonvolatile register programming in Internal Memory chapter.
■ Added explanation of reset value to FMPRE0/1/2/3, FMPPE0/1/2/3, USER_DBG, and USER_REG0/1
registers.
■ Changed buffer type for WAKE pin to TTL and HIB pin to OD.
■ In ADC characteristics table, changed Max value for GAIN parameter from ±1 to ±3 and added E_IR
(Internal voltage reference error) parameter.
■ Additional minor data sheet clarifications and corrections.
