Updated “System Overview” on page 13 with a voltage range specification for the internal oscillator.
Updated Table 2.10 on page 34 with new conditions for the internal oscillator accuracy. The internal
oscillator accuracy is dependent on the operating voltage range.
Updated Section 2 to remove the internal oscillator curve across temperature diagram.
Updated Figure “4.5 12-Bit ADC Burst Mode Example with Repeat Count Set to 4” on page 58 with new
timing diagram when using CNVSTR pin.
Updated SFR Definition 5.1 (REF0CN) with oscillator suspend requirement for ZTCEN.
Updated SFR Definition 6.1 (REG0CN) with a new definition for Bit 6. The bit 6 reset value is 1b and
must be written to 1b.
Updated Section “8.3.3. Suspend Mode” on page 90 with note regarding ZTCEN.
Updated Section “17. LIN (C8051F520/0A/3/3A/6/6A and C8051F530/0A/3/3A/6/6A)” on page 163 with
a voltage range specification for the internal oscillator.
