All buffers should also be 32-bit aligned and DMA capable to prevent extra allocations and copying.
When DMA reading (even in polling mode) the ESP32 always read in 4-byte chunks even if less is requested.
Extra space will be zero filled. Always ensure the out buffer is large enough to hold at least 4 bytes!
