1. The test is performed with the following enabled digital blocks: 2 x GPT, 2 x SPI, 2 x USART, IPC, DMA, 2 x I²C, AES,
TRNG. The value is calculated by measuring the difference in the supply current with and without QFS enabled and running.

1. The tests are performed with the following enabled digital blocks: 2 x GPT, 2 x SPI, 2 x USART, IPC, DMA, 2 x I²C, AES,
TRNG, QFS. Cortex™ frequency equals to 96 MHz and Cortex™ fetching by RAM. The values are calculated by measuring
the difference in the supply current with and without 8 GPIOs enabled and toggling at the given frequency.
