0 An internal temperature proportional voltage V
1 Bandgap reference voltage V
High Temperature Enable Bit — This bit enables the high temperature sensor.
0 The temperature sense is disabled.
1 The temperature sense is enabled.
High Temperature Detect Status Bit — This read-only status bit reflects the temperature. status. Writes have
no effect.
0 Junction Temperature is below level T
1 Junction Temperature is above level T
High Temperature Interrupt Enable Bit
0 Interrupt request is disabled.
1 Interrupt will be requested whenever HTIF is set.
High Temperature Interrupt Flag — HTIF — High Temperature Interrupt Flag
HTIF is set to 1 when HTDS status bit changes. This flag can only be cleared by writing a 1.
Writing a 0 has no effect. If enabled (HTIE=1), HTIF causes an interrupt request.
0 No change in HTDS bit.
1 HTDS bit has changed.
