Shaft
Indicator of Reference Position. If
Shaft
=
‘0’, the reference position is the maximum
inner position, whereas if
Shaft
= ‘1’, the
reference position is the maximum outer
position.
SecPos[10:0]
Secure Position of the stepper motor. This
is the position to which the motor is driven
in case of a
GotoSecurePosition
command, or if the HW-pin is disconnected
from Vbat or Gnd.
If
SecPos[10:0]
= “100 0000 0000”, this
means that Secure Position is disabled, e.g.
the steppermotor will be kept in the
position occupied at the moment these
events occur.
The Secure Position is coded on 11 bits
only, providing actually the most significant
bits of the position, the non coded least
significant bits being set to ‘0’.
Vmax[3:0]
Maximum velocity, minimum velocity and
Vmin[3:0]
Acc[3:0]
acceleration of the stepper motor are
programmed by coding the respective
Vmax, Vmin and Acc parameters index as
defined in § 8 Positioning Data.
Parameters stored at address 0x00 and 0x01 and bit
LOCKBT
are already programmed in the OTP memory at
circuit delivery, they correspond to the calibration of the
circuit and are just documented here as an indication.
Each OPT bit is at ‘0’ when not zapped. Zapping a bit will
set it to ‘1’. Thus only bits having to be at ‘1’ must be
zapped. Zapping of a bit already at ‘1’ is disabled.
Each OTP byte will be programmed separately (see
command
SetOTPparam
).
Once OTP programming is completed, bit
LOCKBG
can be
zapped, to disable future zapping, otherwise using a
SetOTPparam command could still zap any OTP bit at ‘0’.
The command used to load the application parameters via
the I
2
C bus in the RAM prior to an OTP Memory
programming is
SetMotorParam
. This allows for a
functional verification before using a
SetOTPparam
command to program and zap separately one OTP memory
byte. A
GetOTPparam
command issued after each
SetOTPparam
command allows verifying the correct byte
zapping.
Note
Zapped bits will really be “active” after a
GetOTPparam
or a
ResetToDefault
command or after a power-up.
