47 / 84 page ![]() Data Sheet ADP1053 Rev. A | Page 47 of 84 STATUS_BYTE COMMAND This command returns the lower byte of the STATUS_WORD command. A value of 1 in this command indicates that a fault has occurred. Table 16. Command 0x78—STATUS_BYTE Bits Bit Name R/W Description 7 BUSY R Always reads 0. Not supported. 6 PSON_OFF R Always reads 0. Not supported. 5 VOUT_OV R Always reads 0. Not supported. 4 IOUT_OC R Always reads 0. Not supported. 3 VIN_UV R Always reads 0. Not supported. 2 TEMPERATURE R Always reads 0. Not supported. 1 CML R 1 = communications, memory, or logic fault. 0 NONE_OF_THE_ ABOVE R Always reads 0. Not supported. STATUS_WORD COMMAND A value of 1 in this command indicates that a fault has occurred. Table 17. Command 0x79—STATUS_WORD Bits Bit Name R/W Description 15 VOUT R Always reads 0. Not supported. 14 IOUT/POUT R Always reads 0. Not supported. 13 INPUT R Always reads 0. Not supported. 12 MFR R Always reads 0. Not supported. 11 POWER_GOOD# R Always reads 0. Not supported. 10 FANS R Always reads 0. Not supported. 9 OTHER R Always reads 0. Not supported. 8 UNKNOWN R Always reads 0. Not supported. 7 BUSY R Always reads 0. Not supported. 6 PSON_OFF R Always reads 0. Not supported. 5 VOUT_OV R Always reads 0. Not supported. 4 IOUT_OC R Always reads 0. Not supported. 3 VIN_UV R Always reads 0. Not supported. 2 TEMPERATURE R Always reads 0. Not supported. 1 CML R 1 = communications, memory, or logic fault. 0 NONE_OF_THE_ ABOVE R Always reads 0. Not supported. 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 × 2N). 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 × 2N). [10:8] High bits R Mantissa high bits (Y[10:8]) used in linear mode format (X = Y × 2N). [7:0] Low byte R Mantissa low byte (Y[7:0]) used in linear mode format (X = Y × 2N). 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 × 2N). [10:8] High bits R Mantissa high bits (Y[10:8]) used in linear mode format (X = Y × 2N). [7:0] Low byte R Mantissa low byte (Y[7:0]) used in linear mode format (X = Y × 2N). |
