CHAPTER 7 INTERRUPT
●
Hardware interrupt suppression by interrupt suppression instruction
The ten types of hardware interrupt suppression instructions listed in Table 7.4-2 ignore interrupt requests
without detecting whether a hardware interrupt request exists.
Table 7.4-2 Hardware Interrupt Suppression Instruction
Instructions that do not
accept interrupt and hold
requests
Even if a valid hardware interrupt request is generated during execution of one of these instructions, the
interrupt is not processed until the first time an instruction of a different type is executed.
●
Hardware interrupt suppression during execution of software interrupt
When a software interrupt is activated, the I flag is cleared to "0". In this state, other interrupt requests
cannot be accepted.
