Direct Memory Access
Overview
The pdma module is part of the DMA (Direct Memory Access) driver designed
for ESP chips. Of the Espressif chip range, only ESP32 and ESP32-S2 use
the PDMA type of direct memory access.
This module provides efficient direct data transfer capabilities between peripherals and memory without involving the CPU. It enables bidirectional data transfers through DMA channels, making it particularly useful for high-speed data transfers, such as SPI and I2S communication.
