15.2 Main Control and Register, OTP Memory + ROM
15.2.1. Power-up Phase
The power-up phase of the AMIS-30624 will not exceed 10ms. After this phase, the AMIS-30624 is in shutdown mode, ready to receive
I
C messages and execute the associated commands. After power-up, the registers and flags are in the reset state; some of them
being loaded with the OTP memory content (see Table 18).
15.2.2. Reset State
After power-up, or after a reset occurrence (e.g. a micro cut on pin VBB has made Vdd 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 18 and Table 19.
15.2.3. 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
to avoid an attempt of the circuit to achieve the motion (seeTable 18). The circuit is
then ready to execute a new positioning command, provided thermal and electrical conditions allow for it.
15.2.4. Thermal Shutdown Mode
When thermal shutdown occurs, the circuit performs a
SoftStop
command and goes to motor shutdown mode (see Figure 15).
