Main Control and Register, OTP memory + ROM
Power−up Phase
10ms. After this phase, the AMIS−30621 is in standby
mode, ready to receive LIN messages and execute the
associated commands. After power−up, the registers and
flags are in the reset state, while some of them are being
loaded with the OTP memory content (see Table 19).

level), the H−bridges will be in high−impedance mode, and
the registers and flags will have a predetermined value. This
is documented in Tables 19 and 20.
Soft Stop
with a deceleration phase. At the end of this action, the
register <TagPos> is loaded with the value contained in
register <ActPos>, see Table 19). The circuit is then ready
to execute a new positioning command, provided thermal
and electrical conditions allow for it.
Power up phase of the AMIS−30621 will not exceed

Sleep Mode
driven to its secure position. After which, the circuit is
completely powered down, apart from the LIN receiver,
which remains active to detect a dominant state on the bus.
In case sleep mode is entered while a motion is ongoing, a
transition will occur towards secure position as described in
Positioning and Motion Control provided <SecPos> is
enabled. Otherwise, <SoftStop> is performed.
Sleep mode can be entered in the following cases:

The circuit receives a LIN frame with identifier 0x3C
and first data byte containing 0x00, as required by LIN
specification rev 1.3. See also Sleep in the LIN
Application Command section.
In case the LIN bus is and remains inactive (or is lost)
during more than 25000 time slots (1.30 s at
19.2 kbit/s), a time−out signal switches the circuit to
sleep mode.
