Address-Match Interrupt
Reading address 00000
Setting the stack pointer
An address-match interrupt is generated when the address-match interrupt address register contents match the
program counter value. Two address-match interrupts can be set, each of which can be enabled and disabled by an
address-match interrupt enable bit. The interrupt enable flag (I flag) does not affect address-match interrupts and
processor interrupt priority level (IPL).
Note: When the external data bus width is set to 8 bits, the address match interrupt cannot be used for external areas.
Figure 1.40 shows the address-match interrupt-related registers.
When maskable interrupt occurs, the CPU reads the interrupt information (the interrupt number and interrupt request
level) in the interrupt sequence. The interrupt request bit of the interrupt written in address 00000
Do not read address 00000
rupt source request bit to "0". Though the interrupt is generated, the interrupt routine may not be executed.
The value of the stack pointer immediately after reset is initialized to 0000
value in the stack pointer may cause program runaway. Be sure to set a value in the stack pointer before accepting an
interrupt.
When using the NMI interrupt, initialize the stack pointer at the beginning of a program. Generating any interrupts
including the NMI interrupt is prohibited for the first instruction immediately after reset.
