The I flag enables or disables the maskable interrupt. Setting the I flag to “1” (= enabled) enables the maskable
interrupt. Setting the I flag to “0” (= disabled) disables all maskable interrupts.
The IR bit is set to “1” (= interrupt requested) when an interrupt request is generated. Then, when the interrupt
request is accepted and the CPU branches to the corresponding interrupt vector, the IR bit is cleared to “0” (=
interrupt not requested).
The IR bit can be cleared to “0” in a program. Note that do not write “1” to this bit.
Interrupt priority levels can be set using the ILVL2 to ILVL0 bits.
Table 12.3 shows the Settings of Interrupt Priority Levels and Table 12.4 shows the Interrupt Priority Levels
Enabled by IPL.
The following are conditions under which an interrupt is accepted:
The I flag, IR bit, ILVL2 to ILVL0 bits and IPL are independent of each other. In no case do they affect one
another.
