Notes:

1. Data based on a differential IDD measurement between reset configuration (timer counter running at fCPU/4) and timer

counter stopped (only TIMD bit set). Data valid for one timer.

2. Data based on a differential IDD measurement between reset configuration (timer stopped) and timer counter enabled

(only TCE bit set).

3. Data based on a differential IDD measurement between reset configuration (SPI disabled) and a permanent SPI master

communication at maximum speed (data sent equal to 55h).This measurement includes the pad toggling consumption.

4. Data based on a differential IDD measurement between SCI low power state (SCID=1) and a permanent SCI data trans-

mit sequence.

5. Data based on a differential IDD measurement between reset configuration (I2C disabled) and a permanent I2C master

communication at 100kHz (data sent equal to 55h). This measurement include the pad toggling consumption (27kOhm

external pull-up on clock and data lines).

6. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
