Functions
Indicates a storage address for an instruction to be next taken into an instruction queue buffer.
Temporarily stores an instruction which has been taken from a memory. Consists of 10 bytes.
Indicates an address where data will be next read from or written to.
Temporarily stores data which has been read from internal memory, internal peripheral devices, and
external areas by the BIU; or temporarily stores data which is to be written to internal memory, internal
peripheral devices, and external areas by the CPU or DMAC. Consists of 32 bits.
