Updated “1. System Overview” with a voltage range specification for the internal oscillator.
Updated Table 5.6 on page 47 with new conditions for the internal oscillator accuracy. The internal
oscillator accuracy is dependent on the operating voltage range.
Updated “5. Electrical Characteristics” to remove the internal oscillator curve across temperature
diagram.
Updated SFR Definition 10.1 (REG0CN) with a new definition for Bit 6. The bit 6 reset value is 1b and
must be written to 1b.
Updated “21. Local Interconnect Network (LIN)” with a voltage range specification for the internal
oscillator.
Updated “22. Controller Area Network (CAN0)” with a voltage range specification for the internal
oscillator.
Updated SFR Definition 8.1 (REF0CN) with oscillator suspend requirement for ZTCEN.
Updated "16.3 Suspend Mode" with note regarding ZTCEN.
Updated Figure 6.4 with new timing diagram when using CNVSTR pin.
Added Port 2 Event and Port 3 Events to wake-up sources in Section 19.2.1.
Updated LIN Register Definitions 21.9 and 21.10 with correct reset values.
Updated C2 Register Definitions 28.2 and 28.3 with correct C2 and SFR addresses.
