CHAPTER  7   INTERRUPT/EXCEPTION  PROCESSING  FUNCTION 

 

 

143

User’s Manual  U15195EJ5V0UD

7.3 Maskable 

Interrupts 

 

Maskable interrupt requests can be masked by interrupt control registers.  The V850E/IA2 has 47 maskable 

interrupt sources. 

If two or more maskable interrupt requests are generated at the same time, they are acknowledged according to 

the default priority.  In addition to the default priority, eight levels of priorities can be specified by using the interrupt 

control registers (programmable priority control).  

When an interrupt request has been acknowledged, the acknowledgment of other maskable interrupt requests is 

disabled and the interrupt disabled (DI) status is set.  

When the EI instruction is executed in an interrupt servicing routine, the interrupt enabled (EI) status is set, which 

enables servicing of interrupts having a higher priority than the interrupt request in progress (specified by the interrupt 

control register).  Note that only interrupts with a higher priority will have this capability; interrupts with the same 

priority level cannot be nested. 

However, if multiple interrupts are executed, the following processing is necessary. 

 

<1>  Save EIPC and EIPSW in memory or a general-purpose register before executing the EI instruction. 

<2>  Execute the DI instruction before executing the RETI instruction, then reset EIPC and EIPSW with the values 

saved in <1>. 

 

7.3.1  Operation  

If a maskable interrupt occurs by INT input, the CPU performs the following processing, and transfers control to a 

handler routine. 

 

(1)   Saves the restored PC to EIPC. 

(2)   Saves the current PSW to EIPSW. 

(3)   Writes an exception code to the lower halfword of ECR (EICC). 

(4)   Sets the ID bit of the PSW and clears the EP bit. 

(5)   Sets the handler address corresponding to each interrupt to the PC, and transfers control. 

 

The servicing configuration of a maskable interrupt is shown in Figure 7-4.
