Table 275 - DSP Processor Status
Bit
Description
0
If bits 0, 1 and 2 are 0, the DSP is ready.
Anything else, the DSP is either starting up
1
or changing configuration.
2
3
Spare
4
DSP memory fault.
5
DSP FLASH/RAM CRC discrepancy.
6
Spare
7
DSP Reset/Power cycle indication – set
when the DSP is running from a DSP Flash
configuration.
8
High temperature warning.
9
Any SPM active.
10
DSP New Configuration.
11
Spare
12
Any alarm inhibit active.
13
Spare
14
Any expansion bus or module fault (any
expansion module not present/responding
or a configuration error).
15
Any calibration error.
Notes
Bit 5: If on recalling a configuration from flash the DSP finds a CRC mismatch, the configuration is
considered corrupt. In this case the module sets bit 5 and load an internal default configuration from
firmware. This presents a corrupt configuration from disrupting the ability to reload the required
configuration from the DSP.
Bit 7: Is briefly set during the start-up sequence but at other times may indicate the DSP has reset or that
configuration by the auxiliary processor has failed (user should initiate another download action to make
sure the module is correctly configured and to clear this indication).
Bit 10: Set when the DSP receives a different configuration, unset at power-up or when it receives the
same configuration gain. As the auxiliary processor helps prevent internal configuration when there are
no changes. DSP receives the same data again when only configuration data has changed or irrespective
of any change, if DSP or an expansion module is in fault status. So when there is a DSP configuration
change, this bit usually stays set until the next power cycle or module reset.
Bits 23-25: Full bandwidth synchronous sampling is available while the speed is between the minimum
and maximum RPM. Between the maximum RPM and 2x the maximum RPM synchronous sampling is
usable but has reduced bandwidth.
Speeds lower than the minimum or >2x the maximum RPM are outside the operating envelope for
synchronous sampling.
NOTE: These are common to any channel/tacho, and therefore it is possible for bits 23/24 to be set at the
same time as bit 25.
