ASBC API Parameters Detail
Brief description of input and output API parameters is in the following paragraphs. Descriptions contain only a verbal description of the
parameter. Values which can variable acquired are described in the header file MC33789.h.
Parameters of the Asbc_Init API function:
•
Spi_Channel (Asbc_SpiChannelType) - logical SPI channel number (not physical SPI channel)
•
Config (Asbc_ConfigType) - input configuration structure:
•
Asbc_SafingThreshold0 - 8 bits safing 0 threshold value
•
Asbc_SafingDwellExt0 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold0
•
Asbc_SafingThreshold1 - 8 bits safing 1 threshold value
•
Asbc_SafingDwellExt1 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold1
•
Asbc_SafingThreshold2 - 8 bits safing 2 threshold value
•
Asbc_SafingDwellExt2 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold2
•
Asbc_SafingThreshold3 - 8 bits safing 3 threshold value
•
Asbc_SafingDwellExt3 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold3
•
Asbc_SafingThreshold4 - 8 bits safing 4 threshold value
•
Asbc_SafingDwellExt4 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold4
•
Asbc_SafingThreshold5 - 8 bits safing 5 threshold value
•
Asbc_SafingDwellExt5 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold5
•
Asbc_SafingThreshold6 - 8 bits safing 6 threshold value
•
Asbc_SafingDwellExt6 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold6
•
Asbc_SafingThreshold7 - 8 bits safing 7 threshold value
•
Asbc_SafingDwellExt7 - extension of the arming pulse width (either 255 ms or 2.0 s) for threshold7
Parameters of the Asbc_GetStatus API function:
•
Spi_Channel (Asbc_SpiChannelType) - logical SPI channel number (not physical SPI channel)
•
Status (Asbc_StatusType) output status structure containing the common status of the ASBC device:
•
Asbc_VregSyncSuppOverTemp - Sync supply over-temperature error
•
Asbc_VregSensRegulOverTemp - DC sensor regulator over-temperature error
•
Asbc_VregBoostOverTemp - Boost supply over-temperature error
•
Asbc_VregIgnState
•
Asbc_WakeupPinState - wake-up pin state
•
Asbc_WdogState - watchdog state
•
Asbc_WdogErrStatus - watchdog error status
•
Asbc_SafingSequenceErr - safing sequence error
Asbc_ReadSensor
Spi_Channel [in]
SequenceIdentifier [in]
LogicalChannel [in]
Asbc_ReturnType
This function provides sensor request/response to retrieve sensor
data from satellite interface block.
Asbc_FeedWatchdog
Spi_Channel [in]
WD_Polarity [in]
Asbc_ReturnType
Update the ASBC Watchdog. A successful watchdog refresh is an
SPI command (high), following another SPI command (low).
Asbc_ProgramCmd
Spi_Channel [in]
Command [in]
Data [in]
SpiResponse [out]
Asbc_ReturnType
Send any ASBC command to the device and read its response.
