Torch / Video
The torch/video mode is activated when the SELFL bit
is low. In this case, the pulse width and delays registers are
irrelevant, the time out is de ? activated. The output current
is setup by the contain of the TILED register. In addition,
Similarly, the external NMOS are deactivated (Vgs1 =
Vgs2 = 0) and the ILED current is controlled by the built ? in
current mirrors, the maximum current being 100 mA per
LED.
the time out is immediately activated if the contain of the
TILED register exceeds $3F.
