Implementation Guide: LP_SPI.md - Technical details for quad-mode pin configuration

Notes

Very high CPU frequency; DWT-based timing and interrupt thresholds are critical for stability.
OctoWS2811 and SmartMatrix can offload large parallel outputs; ensure pin mappings and DMA settings match board wiring.
