Interrupt priority levels are set by the interrupt priority select bit in an interrupt control register. When an
interrupt request is generated, the interrupt priority level of this interrupt is compared with the processor
interrupt priority level (IPL). This interrupt is enabled only when its interrupt priority level is greater than
the processor interrupt priority level (IPL). This means that you can disable any particular interrupt by
setting its interrupt priority level to 0.
Table 5.2.1 shows how interrupt priority levels are set. Table 5.2.2 shows interrupt enable levels in
relation to the processor interrupt priority level (IPL).
The following lists the conditions under which an interrupt request is acknowledged:
• Interrupt enable flag (I flag)
• Interrupt request bit
• Interrupt priority level
The interrupt enable flag (I flag), interrupt request bit, interrupt priority level select bit, and the processor
interrupt priority level (IPL) all are independent of each other, so they do not affect any other bit.
When the processor interrupt priority level (IPL) or the interrupt priority level of some interrupt is
changed, the altered level is reflected in interrupt handling at the following timing:
• If the processor interrupt priority level (IPL) is changed by an REIT or FREIT instruction, the changed
• If the processor interrupt priority level (IPL) is changed by a POPC, LDC, or LDIPL instruction, the
• If the interrupt priority level of a particular interrupt is changed by an instruction such as MOV, the

changed level takes effect beginning with the next instruction.
changed level takes effect beginning with the instruction that is executed two clock or two clock peri-
ods after the last clock of the instruction used.
