1.2.24 Read Temperature Value

Description

The SPI command “Read Temperature Value” returns the temperature value of the latest measurement, which is stored in calib.sramTEMPH and calib.sramTEMPL.

Command Frame


Host	0x19	0x00	0x00	0x00
ATA8510/15	events.system	events.events	tempVal_high	tempVal_low

Parameters

0x19 – Command ID
0x00 – Dummy byte (no information)
0x00 – Dummy byte (no information)
0x00 – Dummy byte (no information)

Return Values

events.system – Event byte (for details see SPI command “Get Event Bytes”)
events.events – Event byte (for details see SPI command “Get Event Bytes”)
tempVal_high – calib.sramTEMPH
tempVal_low – calib.sramTEMPL

The interpretation of the return values is not content of this document. The customer shall read the temperature value via the SPI command “Read SRAM / Register” from the SRAM variable calib.tempMeas as described in section Temperature Measurement of Industrial User's Guide (DS50003142).
