Logic Truth Table	T1	T2	State description
M Flash mode	High level (floating)	High level (floating)	The two setting ports of T1 and T2 are floating, and no level is connected.
L Self-locking mode	High level (floating)	Low level (grounding)	D0-D3 independent output latch state, flipping when valid signal detected
H Interlocking mode	Low level (grounding)	High level (floating)	D0-D3 interlock output, the current signal output remains unique
Reserved mode	Low level (grounding)	Low level (grounding)	Other function modes can be customized (not used yet)

Note: To confirm that the setting is valid, the red DK tool board needs to be powered on and reset, every time after setting the T1 and T2 states
