Movement Auto Shut-Off time
When used as a movement Auto Shut-Off module,
several timing options are available. All timings are
derived from the on chip oscillator and have thus the
same tolerance.
If the module is left immobile for a time longer than
TASO the auto shut-off function becomes active.
There is also an additional time period TADI. This
time is valid only in the vertical state and determines
the time between shut-off and the start of the led
blinking.

Position Auto Shut-Off
When used as a position Auto Shut-Off module,
several timing options are available. All timings are
derived from the on chip oscillator and have thus the
same tolerance.
Three different time delays can be defined: the
horizontal shut-off (TH), the vertical shut-off (TV) and
the down shut-off (TD).

Start up sequence
When connecting the asic to the AC line the asic first
passes through a startup sequence. The duration of
this sequence is 1.25 or 3.75 seconds depending on
the duration of phase 1. After the start up test the
normal function of the chip begins. This sequence
