Interrupts
Table 1.9.3. Settings of interrupt priority levels
Interrupt Enable Flag (I flag)
Interrupt Request Bit
Interrupt Priority Level Select Bit and Processor Interrupt Priority Level (IPL)
Interrupt priority
level select bit
The interrupt enable flag (I flag) controls the enabling and disabling of maskable interrupts. Setting this
flag to “1” enables all maskable interrupts while setting it to “0” disables all maskable interrupts. This flag
is set to “0” after reset.
The interrupt request bit is set to “1” by hardware when an interrupt is requested. After the interrupt is
accepted and jumps to the corresponding interrupt vector, the request bit is set to “0” by hardware. The
interrupt request bit can also be set to “0” by software. (Do not set this bit to “1”).
Set the interrupt priority level using the interrupt priority level select bit, which is one of the component bits
of the interrupt control register. When an interrupt request occurs, the interrupt priority level is compared
with the IPL. The interrupt is enabled only when the priority level of the interrupt is higher than the IPL.
Therefore, setting the interrupt priority level to “0” disables the interrupt.
Table 1.9.3 shows the settings of interrupt priority levels and Table 1.9.4 shows the interrupt levels
enabled, according to the contents of the IPL.
The following are conditions under which an interrupt is accepted:
· interrupt enable flag (I flag) = “1”
· interrupt request bit = “1”
· interrupt priority level > IPL
The interrupt enable flag (I flag), the interrupt request bit, the interrupt priority select bit, and the IPL are
independent, and so, not affected by one another.
