CHAPTER  3   CPU  ARCHITECTURE 

 

User’s Manual  U18172EJ2V0UD 

34 

(a)  Interrupt enable flag (IE) 

This flag controls interrupt request acknowledge operations of the CPU. 

When IE = 0, the interrupt disabled (DI) status is set.  All interrupt requests are disabled.  

When IE = 1, the interrupt enabled (EI) status is set.  Interrupt request acknowledgment is controlled with 

an interrupt mask flag for various interrupt sources. 

This flag is reset to 0 upon DI instruction execution or interrupt acknowledgment and is set to 1 upon EI 

instruction execution. 

 

(b)  Zero flag (Z) 

When the operation result is zero, this flag is set to 1.  It is reset to 0 in all other cases. 

 

(c)  Auxiliary carry flag (AC) 

If the operation result has a carry from bit 3 or a borrow at bit 3, this flag is set to 1.  It is reset to 0 in all 

other cases. 

 

(d)  Carry flag (CY) 

This flag stores overflow and underflow that have occurred upon add/subtract instruction execution.  It 

stores the shift-out value upon rotate instruction execution and functions as a bit accumulator during bit 

operation instruction execution.
