DATA-WORD INDEX

SPI CLOCK INDEX

RESERVED

THERMAL ALARM FLAG, CHANNEL 0 ONLY

[0] = THERMAL FAULT NOT DETECTED.

1 = THERMAL FAULT DETECTED.

WHEN THE ALARM_THERM_FLAG BIT IS SET, A FAULT WAS DETECTED ON THE DIE ACCORDING TO

THE THERMAL THRESHOLD SET IN THE ALARM_THERM_THRESH BIT. THIS FLAG IS SUBORDINATE

TO THE ALARM_THERM_MASK CONTROL BIT, AND IT AUTOMATICALLY RESETS AFTER ANY READ

FROM THE ALARM STATE REGISTER.

PPMU ALARM FLAG, CHANNEL 0/CHANNEL 1

[0] = PPMU VOLTAGE/CURRENT CLAMP OR STATIC CURRENT LIMIT CONDITION NOT DETECTED.

1 = PPMU VOLTAGE/CURRENT CLAMP OR STATIC CURRENT LIMIT CONDITION DETECTED.

WHEN THE ALARM_PPMU_FLAG_x BIT IS SET, THEN A PPMU VOLTAGE/CURRENT CLAMP OR STATIC

CURRENT LIMIT CONDITION IS DETECTED ON CHANNEL x. THIS FLAG IS SUBORDINATE TO THE

ALARM_PPMU_MASK_x CONTROL BIT, AND AUTOMATICALLY RESETS AFTER ANY READ FROM THE ALARM

STATE REGISTER.

OVERVOLTAGE ALARM FLAG, CHANNEL 0/CHANNEL 1

[0] = OVERVOLTAGE FAULT NOT DETECTED.

1 = OVERVOLTAGE FAULT DETECTED.

WHEN ALARM_OVDH_FLAG IS SET, AN OVERVOLTAGE FAULT CONDITION IS DETECTED ON CHANNEL x

DUTx PIN ACCORDING TO THE THRESHOLD SET IN THE OVDH DAC REGISTER. THIS FLAG IS SUBORDINATE

TO THE ALARM_OVD_MASK_x CONTROL BIT, AND IT AUTOMATICALLY RESETS AFTER ANY READ FROM

THE ALARM STATE REGISTER.

UNDERVOLTAGE ALARM FLAG, CHANNEL 0/CHANNEL 1

[0] = UNDERVOLTAGE FAULT NOT DETECTED.

1 = UNDERVOLTAGE FAULT DETECTED.

WHEN ALARM_OVDL_FLAG_x IS SET, AN UNDERVOLTAGE FAULT CONDITION IS DETECTED ON CHANNEL x

DUTx PIN ACCORDING TO THE THRESHOLD SET IN THE OVDL DAC REGISTER. THIS FLAG IS SUBORDINATE

TO THE ALARM_OVD_MASK_x CONTROL BIT, AND AUTOMATICALLY RESETS AFTER ANY READ FROM THE

ALARM STATE REGISTER.

SPI CLOCK INDEX

PRODUCT SERIALIZATION CODE REGISTER, CHANNEL 0/CHANNEL 1

THIS REGISTER CONTAINS UNIQUE NONVOLATILE PRODUCT IDENTIFICATION INFORMATION THAT IS

WRITTEN TO THE DEVICE DURING MANUFACTURE. THIS REGISTER IS INITIALIZED DURING RESET TO

THE DATA TRIMMED INTO NONVOLATILE FUSE MEMORY. WHILE IT IS POSSIBLE TO WRITE SOME

TEMPORARY DATA TO THIS REGISTER, IT HAS NO EFFECT ON OPERATION OF THE DEVICE. THE

CONTENTS OF THE REGISTER ARE REINITIALIZED AT NEXT RESET TO THE FACTORY PROGRAMMED

VALUES. THERE ARE 32 BITS OF IDENTIFICATION DATA CONTAINED IN THIS REGISTER, AS FOLLOWS:

CHAN 0:

PRODUCT SERIALIZATION CODE LOW

(LOWER HALF)

CHAN 1:

PRODUCT SERIALIZATION CODE HIGH (UPPER HALF)
