Bit 15 – OVF Overflow Interrupt Enable

Writing a '0' to this bit has no effect. Writing a '1' to this bit will set the Overflow Interrupt Enable bit, which enables the Overflow interrupt.

Value	Description
0	The Overflow interrupt is disabled.
1	The Overflow interrupt is enabled.

Bit 14 – TAMPER Tamper Interrupt Enable

Writing a '0' to this bit has no effect. Writing a '1' to this bit will set the Tamper Interrupt Enable bit, which enables the Tamper interrupt.

Value	Description
0	The Tamper interrupt it disabled.
1	The Tamper interrupt is enabled.

Bits 8, 9 – ALARMn Alarm n Interrupt Enable

Writing a '0' to this bit has no effect. Writing a '1' to this bit will set the Alarm n Interrupt Enable bit, which enables the Alarm n interrupt.

Value	Description
0	The Alarm n interrupt is disabled.
1	The Alarm n interrupt is enabled.

Bits 0, 1, 2, 3, 4, 5, 6, 7 – PERn Periodic Interval n Interrupt Enable [n = 7..0]

Writing a '0' to this bit has no effect. Writing a '1' to this bit will set the Periodic Interval n Interrupt Enable bit, which enables the Periodic Interval n interrupt.

Value	Description
0	Periodic Interval n interrupt is disabled.
1	Periodic Interval n interrupt is enabled.
