Main Control and Register, OTP memory + ROM
Power−up Phase
10 ms. After this phase, the AMIS−30623 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: RAM
Registers).

level), the H−bridges will be in high−impedance mode, and
the registers and flags will be in a predetermined position.
This is documented in Table 19: RAM Registers and
Table 20: Flags Table.
Soft−stop

circuit is then ready to execute a new positioning command,
provided thermal and electrical conditions allow for it.
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 and <SleepEn> bit = 1. See also
Sleep in the LIN Application Command section.
In case the >SleepEn> bit = 1 and the LIN bus 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.
