FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
by status bits MOV0. Additional details are provided in the
Internal clock Calibration
section.
Some applications may require a guaranteed maximum
pointer velocity and acceleration. Guaranteeing these fall
below 1.0 MHz. The frequency range of the calibrated clock
maximums requires [
that
deleted PV]
the nominal internal
clock frequency will always be below 1.0 MHz if bit PE4 is
Logic [0] when initiating a calibration command, followed by
an 8.0
μ
s reference pulse. The frequency will be centered at
1.0 MHz if bit PE4 is Logic [1]. Some applications may require
a slower calibrated clock due to a lower motor gear reduction
ratio. Writing Logic [1] to bit PE2 will slow the internal
oscillator by one-third. Slowing the oscillator accommodates
a longer calibration pulse without overrunning the internal
counter - a condition designed to generate a CAL fault
indication. For example, calibration for a clock frequency of
667 kHz would require a calibration pulse of 12
μ
s. Unless the
internal oscillator is slowed by writing PE2 to Logic [1], a 12
μ
s calibration pulse may overrun the counter and generate a
CAL fault indication.
Some applications may require faster pointer positioning
than is provided with the air core motor emulation feature.
Writing Logic [1] to bit PE5 will disable the air core emulation
for both gauges and provide an acceleration and deceleration
at the maximum that the velocity position ramp can provide.
Bit PE6 must always be written Logic [0] during all PECCR
writes if the device is being used to drive an MMT style motor.
Similarly, this bit must always be written as Logic [1] when
being used to control Switec style motors.
The default Pointer Position 0 (PE7 = 0) will be the farthest
counter-clockwise position. A Logic [1] written to bit PE7 will
change the location of the position 0 for the gauge to the
farthest clockwise position. The pointer will always move
towards position 0 when executing an RTZ. Exercise care
when writing to PECCR bit PE7 in order to prevent an
accidental change of the position 0 location.
Bits PE11:PE9 determine the content of the bits clocked
out of the SO pin. When bit PE11 is at Logic [0], the clocked
out bits will provide device status. If Logic [1] is written to bit
PE11, the bits clocked out of the SO pin, depending upon the
state of bits PE10:PE9, provides either:
Accumulator information and detection status during
the RTZ (PE10 Logic [0])
Real time pointer position location at the time
CS
goes
low (PE10 Logic [1] and PE9 Logic [0]), or
The real time step position of the pointer as described
in the velocity
Table 6
(PE10 and PE9 Logic [1]).
Additional details are provided in the
SO Communication
section.
If bit PE12 is Logic [1] during a PECCR command, the
state of PE11:PE0 is ignored. This is referred to as the null
command and can be used to read device status without
affecting device operation.
The bits in
Table 9
are
write-only
.
Null Command for Status Read (PE12) Bit D12
0 = Disable
1 = Enable
Status Select (PE11) Bit D11
This bit selects the information clocked out of the SO pin.
0 = Device Status (the logic states of PE10, and PE9
are don’t cares)
1 = RTZ Accumulator Value, Gauge Pointer position, or
Gauge Velocity ramp position (depending upon the
logic states of PE10, and PE9)
RTZ Accumulator or Pointer Status Select (PE10) Bit D10
This bit is recognized only when PE11 = 1.
0 = RTZ Accumulator Value and status
1 = Pointer Position or Speed
Pointer Position or Pointer Speed Select (PE9) Bit D9
This bit is recognized only if PE11 and PE10 = 1.
0 = Gauge Pointer Position
1 = Gauge Pointer Speed
(PE8) Bit D8
This bit must be transmitted as Logic [0] for valid PECCR
commands.
Position 0 Location Select (PE7) Bit D7
This bit determines the Position 0 of the gauge. RTZ
direction will always be to the position 0.
0 = Position 0 is the most CCW (counterclockwise)
position
1 = Position 0 is the most CW (clockwise) position
Motor Type Selection (PE6) Bit D6
0 = MMT Style (coil phase difference = 90°)
1 = Switec Style (coil phase difference = 60°)
