22.4 Software Interrupt Acknowledgment Operations

A software interrupt is acknowledged in response to execution of a BRK or BRKCS instruction. Software interrupts

cannot be disabled.

22.4.1 BRK instruction software interrupt acknowledgment operation

When a BRK instruction is executed, the program status word (PSW) and program counter (PC) are saved in that

order to the stack, the IE flag is cleared (0), the vector table (003EH/003FH) contents are loaded into the lower 16

bits of the PC, and 0000B into the higher 4 bits, and a branch is performed (the start of the service program must be

in the base area).

The RETB instruction must be used to return from a BRK instruction software interrupt.

Caution The RETI instruction must not be used to return from a BRK instruction software interrupt.

22.4.2 BRKCS instruction software interrupt (software context switching) acknowledgment operation

The context switching function can be initiated by executing a BRKCS instruction.

The register bank to be used after context switching is specified by the BRKCS instruction operand.

When a BRKCS instruction is executed, the program branches to the start address of the interrupt service program

(which must be in the base area) stored beforehand in the specified register bank, and the contents of the program

status word (PSW) and program counter (PC) are saved in the register bank.

Figure 22-8. Context Switching Operation by Execution of a BRKCS Instruction

The RETCSB instruction is used to return from a software interrupt due to a BRKCS instruction. The RETCSB

instruction must specify the start address of the interrupt service program for the next time context switching is

performed by a BRKCS instruction. This interrupt service program start address must be in the base area.

Caution The RETCS instruction must not be used to return from a BRKCS instruction software interrupt.
