– replaced VREF with VAREF in Note 3

– added Note 4 to LQFP44 pin No. 22

2. Table 30: I/O port configuration on page 79:

– modified Input and Output table headers

– changed configuration of pin PE2 and modified Note 1

3. Table 104: Current characteristics on page 192:

– changed maximum value for output current sunk by any standard I/O and control

pin

– changed maximum value for output current sunk by any high sink I/O pin

– added “Injected current on PC6 pin (Flash devices only)” to IINJ(PIN) ratings

– reorganized footnotes

– modified Note 3

4. Table 110: Current consumption on page 196: Changed Flash device typical and

maximum values in Active Halt mode

5. Table 120: Dual voltage HDFlash memory on page 203:

– changed data retention conditions and minimum value

– replaced TA=25°C with TA=85°C in conditions for NRW

6. Table 134: 10-bit ADC characteristics on page 220:

– modified parameter for input leakage current

– removed negative input leakage current parameter

– added Note 2

7. Table 135: ADC accuracy on page 223

– added maximum values specific to 32 Kbyte Flash devices only

– added conditions to total unadjusted error, to offset error and to gain error

– redistributed footnotes

– modified Note 1

8. Table 141: Flash option bytes on page 228:

– Option byte 0: Changed OPT1 to reserved

– Option byte 1: Replaced OPT7 default value with Note 1

– Option byte 1: Changed OPT3 default value of from 1 to 0

9. Table 142: Option byte 0 bit description on page 228: Changed OPT1 to reserved

10. Table 143: Option byte 1 bit description on page 229: Modified function description for

OPT3:1
