READ TEMPERATURE COMMANDS
The READ_TEMPERATURE_1 and READ_TEMPERATURE_2 commands return the temperature for RTD1 and RTD2, respectively, in
linear mode format (X = Y × 2
N
).
Table 18. Command 0x8D—READ_TEMPERATURE_1
Bits Bit Name R/W Description
[15:11] Exponent R Return the exponent (N) used in linear mode format (X = Y × 2
N
).
[10:8] High bits R Mantissa high bits (Y[10:8]) used in linear mode format (X = Y × 2
N
).
[7:0] Low byte R Mantissa low byte (Y[7:0]) used in linear mode format (X = Y × 2
N
).
Table 19. Command 0x8E—READ_TEMPERATURE_2
Bits Bit Name R/W Description
[15:11] Exponent R Return the exponent (N) used in linear mode format (X = Y × 2
N
).

N
).
[7:0] Low byte R Mantissa low byte (Y[7:0]) used in linear mode format (X = Y × 2
N
).
