This register is used to monitor various interrupt event settings and the conditions under which various interrupt-

 

related events occur.

 

 

 

 

 

 

 

 

1) TI / TP bit ( Interrupt Signal Output Mode Select. Interrupt / Periodic )

When a fixed-cycle timer interrupt event occurs (when the TF bit goes from "0" to 1") , this bit specifies whether the interrupt operation occurs just once or repeatedly.

Writing "1" to this bit sets repeated operation. Writing "0" to this bit sets single-shot operation.

∗For details, see "9.2. Fixed-cycle Timer Interrupt Function ".

2)AF bit ( Alarm Flag )

This is a flag bit that retains the result when an alarm interrupt event has been detected.

When an alarm interrupt event occurs, this bit's value changes from "0" to "1".

∗For details, see "9.3. Alarm Interrupt Function".

3)TF bit ( Timer Flag )

This is a flag bit that retains the result when a fixed-cycle timer interrupt event has been detected. When a fixed-cycle timer interrupt event occurs, this bit's value changes from "0" to "1".

∗For details, see "9.2. Fixed-cycle Timer Interrupt Function ".

4)AIE bit ( Alarm Interrupt Enable )

This bit sets the operation of the /INT interrupt signal when an alarm interrupt event has occurred (the AF bit value changes from "0" to "1").

When a "1" is written to this bit, occurrence of an interrupt event causes a low-level interrupt signal to be output from /INT pin.

Writing "0" to this bit prohibits low-level output from the /INT pin.

∗For details, see "9.3. Alarm Interrupt Function".

5)TIE bit ( Timer Interrupt Enable )

This bit sets the operation of the /INT interrupt signal when a fixed-cycle interrupt event has occurred (the TF bit value changes from "0" to "1").

When a "1" is written to this bit, occurrence of an interrupt event causes a low-level interrupt signal to be output from /INT pin.

Writing "0" to this bit prohibits low-level output from the /INT pin.

∗For details, see "9.2. Fixed-cycle Timer Interrupt Function ".
