FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
bit will continue to indicate Logic [1] until the SPI message
following a detection of the zero position, or after the RTZ
feature is commanded OFF using the RTZ message.
0 = Return to Zero disabled
1 = Return to Zero enabled successfully
[Corrected original entry above to ACC2]
(ACC14:ACC0) Bits OD14:OD0
These 15 bits are from the RTZ accumulator. They
represent the integrated signal present on the non-driven coil
during an RTZ event. These bits are Logic [0] after power-on
reset, or after the
RST
pin transitions from Logic [0] to [1].
After an RTZ event, they will represent the last RTZ
accumulator result before the RTZ was stopped.
ACC14 is the MSB and is the sign bit used for zero
detection. Negative numbers have MSB Logic [1] and are
coded in twos complement.
Figure 13. RTZ Accumulator (Typical)
The analog-to-digital converter's linear input range covers
the expected magnitude of motor back e.m.f. signals, which
is usually less than 500mV. Input signals greater than this will
not cause any damage (the circuit is connected to the motor
H-Bridge drivers, and thus is exposed to the full magnitude of
the drive voltages), but may cause some small loss of
linearity. A typical plot of output vs. input is shown in
Figure 13
for 4ms step times.
GAUGE POINTER POSITION STATUS
INFORMATION
Most recent valid PECCR command resulting in the
Gauge Pointer Position status output:
The bits in
Table 18
are
read-only
bits.
(ENB) Bit OD15
This bit indicates whether the Gauge is enabled.
0 = Disabled
1 = Enabled
(DIR) Bit OD14
This bit indicates the direction the Gauge is moving.
0 = Toward position 0
1 = Away from position 0
(DIRC) Bit OD13
This bit is used to determine whether the direction of the
most recent pointer movement is toward the last commanded
position or away from it.
0 = Direction of the pointer movement is toward the
commanded position
1 = Direction of the pointer movement is away from the
commanded position
(CMD) Bit OD12
This bit indicates whether the gauge is at the most recently
commanded position.
0 = At commanded position
1 = Not at commanded position
