FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
? 1 = Return to Zero enabled successfully
ACC14:ACC0 (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
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 8 for 4ms step times.

The bits in Table 17 are read-only bits.
ENB0 (OD15) — This bit indicates whether Gauge 0 is
enabled.
? 0 = Disabled
? 1 = Enabled
DIR0 (OD14) — This bit indicates the direction Gauge 0 is
moving.
? 0 = Toward position 0
? 1 = Away from position 0
DIRC0 (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.
CMD0 (OD12) — This bit indicates whether Gauge 0 is at
the most recently commanded position.
? 0 = At commanded position
? 1 = Not at commanded position
POS11:POS0 (OD11:OD0) — These 12 bits represent the
actual position of the pointer at the time CS transitions to a
logic [0].
