0 = Clock within spec
1 = Clock out of spec
OVUV (OD6) — Undervoltage or Overvoltage Indication. A
logic [1] on this bit indicates the V
PWR
voltage fell to a level
below the V
PWRUV
since the last SPI communication (refer to
the Static Electrical Characteristics table under
POWER
INPUT
, page
5
). An undervoltage event is just flagged, while
an overvoltage event automatically disables the drive
outputs. Because the pointer may not be in the expected
position, the master may want to re-calibrate the pointer with
an RTZ command after the voltage returns to normal level.
For an overvoltage event, both gauges must be re-enabled
as soon as this flag returns to logic [0]. The state machine will
continue to operate properly as long as V
DD
is within the
normal range.
0 = Normal range
1 = Battery voltage fell below V
PWRUV
or exceeded
V
PWROV
MOV1 (OD5) — This bit identifies Gauge 1 Movement
since last SPI communication. A logic [1] on this bit indicates
the Gauge 1 pointer position changed since the last SPI
command. This information allows the master to confirm the
pointer is moving as commanded.
0 = Gauge 1 position has not changed since the last SPI
command
1 = Gauge 1 pointer position has changed since the last
SPI command
MOV0 (OD4) — Gauge 0 Movement Since last SPI
Communication. A logic [1] on this bit indicates the Gauge 0
pointer position has changed since the last SPI command.
This information allows the master to confirm the pointer is
moving as commanded.
0 = Gauge 0 position has not changed since the last SPI
command
1 = Gauge 0 pointer position has changed since the last
SPI command
RTZ1 (OD3) — RTZ1 Is Enabled or Disabled. A logic [1] on
this bit indicates Gauge 1 is in the process of returning to the
zero position as requested with the RTZ command. This bit
will continue to indicate a logic [1] until the SPI message
following a detection of the zero position, or the RTZ feature
is commanded OFF using the RTZ message.
0 = Return to Zero disabled
1 = Return to Zero enabled successfully
RTZ0 (OD2) — RTZ0 Is Enabled or Disabled. A logic [1] on
this bit indicates Gauge 0 is in the process of returning to the
zero position as requested with the RTZ command. This bit
continues to indicate a logic [1] until the SPI message
following a detection of the zero position, or the RTZ feature
is commanded OFF using the RTZ message.
0 = Return to Zero disabled
1 = Return to Zero enabled successfully
OT1 (OD1) — Gauge 1 Junction Overtemperature. A
logic [1] on this bit indicates that the coil drive circuitry
dedicated to drive Gauge 1 has exceeded the maximum
allowable junction temperature since the last SPI
communication and that Gauge 1 has been disabled. It is
recommended that the pointer be re-calibrated using the RTZ
command after re-enabling the gauge using the PECCR
command. This bit remains logic [1] until the gauge is
enabled.
0 = Temperature within range
1 = Gauge 1 maximum allowable junction temperature
condition has been reached
OT0 (OD0) — Gauge 0 Junction Overtemperature. A
logic [1] on this bit indicates that the coil drive circuitry
dedicated to drive Gauge 0 has exceeded the maximum
allowable junction temperature since the last SPI
communication and that Gauge 0 has been disabled. It is
recommended that the pointer be re-calibrated using the RTZ
command after re-enabling the gauge using the PECCR
command. This bit remains logic [1] until the gauge is re-
enabled.
0 = Temperature within range
1 = Gauge 0 maximum allowable junction temperature
condition is reached
RTZ Accumulator Status Information
Most recent valid PECCR command resulting in the RTZ
Accumulator status output:
The bits in
Table 16
are
read-only
bits.
RTZ (OD15) — RTZ Bit Is Enabled or Disabled. A logic [1]
on this bit indicates that the Gauge is in the process of
returning to the zero position as requested with the RTZ
command. This bit will continue to indicate a logic [1] until the
SPI message following a detection of the zero position, or the
RTZ feature is commanded OFF using the RTZ message.
0 = Return to Zero disabled
