FROM TIM to DMA

Refer to Section 2.6: DMA block.

2.2

Analog block

The analog block includes:

•

The ADC block (three ADCs)

•

The DAC block (two DACs)

•

The temperature sensor block

2.2.1

From ADC to ADC

In the multi ADC mode, the start of conversion is triggered alternately or simultaneously by

the ADC1 master to the ADC2 and ADC3 slaves depending on the mode selected by the

MULITI [4:0] bits in the ADC_CCR register.

For more details, refer to multi ADC mode section of RM0385 reference manual.

2.2.2

From the temperature sensor to ADC1

The temperature sensor can be used to measure the ambient temperature (Ta) of the

device.

conversion is performed.

Figure 5 shows the block diagram of the temperature sensor.
