we are planning a project with the iMX DUAL. Low energy consumption is very important in some device states.
Therefore the following question:
Is it possible to transfer via SPI received data (rate 500kHz) via DMA to one of the internal RAMs (TCM or OCRAM) during System Idle mode or even during Low Power Idle mode ?
System Idle mode power consumption is around 30mW
Low Power Idle mode is around 3mW
10.1.4.3 Low Power Modes
The ECSPI does not operate under low power mode.
Thanks in advance
