19.4.4 Interrupt request hold
request acknowledgment is held pending until the end of execution of the next instruction. These instructions (interrupt
request hold instructions) are listed below.
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
There are instructions where, even if an interrupt request is issued for them while another instruction is being executed,
• MOV PSW, #byte
• MOV PSW, A
• MOV1 PSW. bit, CY
• SET1 PSW. bit
• CLR1 PSW. bit
• RETB
• RETI
• POP PSW
• BTCLR PSW. bit, $addr8
• EI
• DI
• SKC
• SKNC
• SKZ
• SKNZ
• Manipulation instructions for the IF0L, IF0H, IF1L, IF1H, IF2L, IF2H, MK0L, MK0H, MK1L, MK1H, MK2L, MK2H,
Caution The BRK instruction is not one of the above-listed interrupt request hold instructions. However, the
Figure 19-18 shows the timing at which interrupt requests are held pending.
Remarks 1. Instruction N: Interrupt request hold instruction
CPU processing
PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L, PR11H, PR12L, and PR12H registers.
software interrupt activated by executing the BRK instruction causes the IE flag to be cleared.
Therefore, even if a maskable interrupt request is generated during execution of the BRK instruction,
the interrupt request is not acknowledged.
2. Instruction M: Instruction other than interrupt request hold instruction
3. The ××PR (priority level) values do not affect the operation of ××IF (interrupt request).
