bit 6

TUPPER and TLOWER Window Lock Bit (Win. Lock):

0 =

Unlocked. TUPPER and TLOWER registers can be written. (power-up default)

1 =

Locked. TUPPER and TLOWER registers can not be written

When enabled, this bit remains set ‘1’ or locked until cleared by internal reset (Section 5.4 “Summary

of Temperature Sensor Power-on Default”). This bit does not require a double-write.

bit 5

Interrupt Clear (Int. Clear) Bit:

0 =

No effect (power-up default)

1 =

Clear interrupt output. When read this bit returns ‘0’

bit 4

Event Output Status (Event Stat.) Bit:

0 =

Event output is not asserted by the device (power-up default)

1 =

Event output is asserted as a comparator/Interrupt or critical temperature output

bit 3

Event Output Control (Event Cnt.) Bit:

0 =

Disabled (power-up default)

1 =

Enabled

This bit can not be altered when either of the lock bits is set (bit 6 and bit 7).

bit 2

Event Output Select (Event Sel.) Bit:

0 =

Event output for TUPPER, TLOWER and TCRIT (power-up default)

1 = TA > TCRIT only. (TUPPER and TLOWER temperature boundaries are disabled.)

When the Alarm Window Lock bit is set, this bit cannot be altered until unlocked (bit 6).

bit 1

Event Output Polarity (Event Pol.) Bit:

0 =

Active low (power-up default)

1 =

Active-high

This bit cannot be altered when either of the lock bits is set (bit 6 and bit 7).

bit 0

Event Output Mode (Event Mod.) Bit:

0 =

Comparator output (power-up default)

1 =

Interrupt output

This bit cannot be altered when either of the lock bits is set (bit 6 and bit 7).
