    CHAPTER 2 MEMORY ARCHITECTURE 2.1.1 Direct Address Area The lower portion of the address space is used for the direct address area. Instructions that specify direct addresses allow you to access this area without the use of general- purpose registers, using only the operand information in the instruction itself. The size of the address area that can be specified by direct addressing varies according to the length of the data being transferred.

    CHAPTER 4 RESET AND "EIT" PROCESSING ■ Vector Table Configuration Vector tables are located in the main memory, occupying an area of 1 Kbyte beginning with the address shown in the TBR. These areas are intended for use as a table of entry addresses for "EIT" processing, however in applications where vector tables are not required, this area can be used as a normal instruction or data area.

    CHAPTER 4 RESET AND "EIT" PROCESSING ■ Saved Registers Except in the case of reset processing, the values of the "PS" and "PC" are saved to the stack as designated by the "SSP", regardless of the value of the "S" flag in the "CCR". No save operation is used in reset processing.

  • Page 61: Interrupts

    CHAPTER 4 RESET AND "EIT" PROCESSING Interrupts Interrupts originate independently of the instruction sequence. They are processed by saving the necessary information to resume the currently executing instruction sequence, and then starting the processing routine corresponding to the type of interrupt that has occurred.

  • Page 62: User Interrupts, Overview Of User Interrupts, Conditions For Acceptance Of User Interrupt Requests

    CHAPTER 4 RESET AND "EIT" PROCESSING 4.3.1 User Interrupts User interrupts originate as requests from peripheral circuits. Each interrupt request is assigned an interrupt level, and it is possible to mask requests according to their level values. This section describes conditions for acceptance of user interrupts, as well as their operation and uses.

  • Page 63: How To Use User Interrupts

    CHAPTER 4 RESET AND "EIT" PROCESSING ■ Time to Start of Interrupt Processing The time required to start interrupt processing can be expressed as a maximum of "n + 6" cycles from the start of the instruction currently executing when the interrupt was received, where "n" represents the number of execution cycles in the instruction.

  • Page 64: Non-maskable Interrupts (nmi)

    CHAPTER 4 RESET AND "EIT" PROCESSING 4.3.2 Non-maskable Interrupts (NMI) Non-maskable interrupts (NMI) are interrupts that cannot be masked. "NMI" requests can be produced when "NMI" external signal pin input to the microcontroller is active. This section describes conditions for the acceptance of "NMI" interrupts, as well as their operation and uses.

  • Page 65

    CHAPTER 4 RESET AND "EIT" PROCESSING ■ "PC" Values Saved for Non-maskable Interrupts When an "NMI" is accepted by the processor, those instructions in the pipeline that cannot be interrupted in time will be executed. The remainder of the instructions will be canceled, and will not be processed after the interrupt.
