we were trying to use the temperature compensation feature for the TPM, everything seems to be as expected until the chamber temperature reaches about -10deg (we start at +60). At that time the TPM always reports 0x1FF for both channels.
reg 0x00B = -50 (0xce)
reg 0x00D = 0x05
reg 0x00F = 0x00
If we clear the temperature offset (reg 0x00B=0) the TPM reports are not stuck anymore
0x06F = 0x02
If we clear the compensation reg (reg 0x06F=0) the TPM reports are not stuck anymore
Is this bug documented somewhere? Is there a workaround?
