Description of Changes

21-Mar-2006

Added “32-Pin LQFP Package Pinout” on page 10

Removed CSS feature in “SYSTEM INTEGRITY MANAGEMENT (SI)” on page 29.

Updated “DEVICE ORDERING INFORMATION AND TRANSFER OF CUSTOMER CODE”

on page 177

Updated “KNOWN LIMITATIONS” on page 186

10-Apr-2006

Removed blank pages

10-Apr-2007

In Table 2 added note for I/O Port E2 (PE2) output mode “pull-up always activated”

Deleted the sentence in Section 4.3.1 ‘Readout protection is not supported if LVD is ena-

bled’

In Section 10.4 16-bit timer, replaced text in note 3 with "In both internal and external clock

modes, OCFi and OCMPi are set while the counter value equals the OCiR register value

(see Figure 50 for an example with fCPU/2 and Figure 51 for an example with fCPU/4). This

behavior is the same in OPM or PWM mode."

Removed Compare Register i Latch signal from Figure 51.

Removed EMC protective circuitry in Figure 87 on page 159 (device works correctly without

these components)

Changed Footnote 4 in Section 12.11.1

Added ‘TIMD set simultaneously with OC interrupt’ in Section 15.1.2

Added ‘Pull-up always active on PE2’ in Section 15.1.8

Deleted limitations ‘Halt ActiveHalt Power consumption’ ‘I2C interrupt exit from Halt/Active-

Halt’ and Safe connection of OSC1/OSC2 pins’ in Section 15

13-Oct-2008

Title of the document changed
