Enumeration Type Documentation

boot_phases

enum boot_phases

Flood fill phases, used in nearest neighbour packets.

Note that these also set the low 8–16 bits of the control word.

Enumerator
FF_START_PHASE_1	Start.
FF_BLOCK_START_PHASE_1	Block start.
FF_BLOCK_DATA_PHASE_1	Block data.
FF_BLOCK_END_PHASE_1	Block end.
FF_CONTROL_PHASE_1	Finish.
