1. Data based on a differential I
DD
measurement between all peripherals OFF and a timer counter running at 16 MHz. The
CPU is in Wait mode in both cases. No IC/OC programmed, no I/O pins toggling. Not tested in production.
2. Data based on a differential I
DD
measurement between the on-chip peripheral in reset configuration and not clocked and
the on-chip peripheral when clocked and not kept under reset. The CPU is in Wait mode in both cases. No I/O pins toggling.
Not tested in production.
3. Peripherals listed above the I
DD(ALL)
parameter ON: TIM1, TIM2, TIM3, TIM4, TIM5, USART1, USART2, USART3, SPI1,
SPI2, I2C1, DMA1, WWDG.
4. Data based on a differential I
DD
measurement between ADC in reset configuration and continuous ADC conversion.
