OTHER SYSTEM STATUS: THERMAL FAULT DETECTED

The I

C registers that control an interrupt generation (INT: HI

→LO) are shown below. The HEX address for each

register is shown by the register name, together with the R or W functionality for the register bits. Shaded values
indicate default initial power-up values.
