DOCUMENT CHANGE LIST
Revision 0.2 to Revision 1.0
ï® Added documentation for 40-pin QFN devices in all relevant chapters.
ï® Change oscillator specification for devices initially specified to have ±1.0% oscillators. All devices are
now rated for ±0.5% across operating voltage and temperature.
ï® Removed all content from â1. System Overviewâafter block diagrams.
ï® Updated â5. Electrical CharacteristicsââUpdated various specifications and filled in all TBD values for
all specifications.
ï® Updated âTable 5.11. Voltage Reference Electrical CharacteristicsââChanged Minimum external
reference input voltage from 0 V to 1 V.
ï® Updated â9. ComparatorsââFixed incorrect references to SFR Definitions 7.x.
ï® Updated âTable 13.1ââAdded SFRs SN0, SN1, SN2, and SN3 to SFR map.
ï® Updated âSFR Definition 19.2â (OSCICN) - Removed errant row for Bit 6. Also, Bit 3 defintion changed
to a Reserved bit from an Unused bit.
ï® Updated â20. Port Input/OutputââAdded Port 4 to the crossbar diagrams and documentation.
ï® Updated â27.4. Watchdog Timer ModeââFixed incorrect references from Module 2 as the watchdog
module to Module 5.ï
Revision 1.0 to Revision 1.1
ï® Updated âOrdering Informationâ on page 20 and Table 2.1, âProduct Selection Guide,â on page 21 to
include -A (Automotive) devices and automotive qualification information.
ï® Updated supply current related specifications throughout â5. Electrical Characteristicsâ.
ï® Updated SFR Definition 8.1 to change VREF high setting to 2.20 V from 2.25 V.
ï® Updated Table 5.12 on page 51 and Figure 9.1 on page 75 to indicate that Comparators are powered
from VIO and not VDDA.
ï® Updated Table 5.12 on page 51 to fix Comparator Supply Current Typical values for Modes 2 and 3.
ï® Updated the Gain Table in â6.3.1. Calculating the Gain Valueâ to fix the ADC0GNH Value in the last row.
