The RGB565 format documentation in embedder.h incorrectly stated that the red component uses the least significant bits. Unit tests in embedder/testdefs/embedder_unittests.cc demonstrate this is incorrect, showing: - Red test (0xF800): Uses bits [15:11] - Green test (0x07E0): Uses bits [10:5] - Blue test (0x001F): Uses bits [4:0] This commit fixes the documentation to correctly reflect the actual bit layout: - Red uses 5 MSBs [15:11] - Green uses 6 middle bits [10:5] - Blue uses 5 LSBs [4:0] Also fixes the example bit extraction code to use correct masks, matching the test expectations. Impact: This change helps prevent potential developer confusion about RGB565 bit ordering and ensures the documentation matches the actual implementation as verified by the test suite.
