Power ? up Phase
Power ? up phase of the AMIS ? 30623 will not exceed
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).
Reset
After power ? up, or after a reset occurrence (e.g. a
micro ? cut on pin V BB has made V DD to go below VddReset
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
A soft ? stop is an immediate interruption of a motion, but
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: Ram Registers). The
circuit is then ready to execute a new positioning command,
provided thermal and electrical conditions allow for it.
Sleep Mode
When entering sleep mode, the stepper ? motor can be
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.
