3 / 21 page  eorex EU1010 Feb.2009 www.eorex.com MCU Description Item Abbreviation Description Accumulator ACC The EU1010 has an 8-bit register used for data hold, exchange, arithmetic, transfer and I/O operation. Index Register (X,Y) In EU1010 that builds in two index registers ( X and Y ). These two index registers could be used to count program steps or to provide an index value to be used in generating as effective address. When executing an instruction which specifies indexed addressing, the MCU fetches the operation code and the base address, and modifies the address by adding the index register to its prior to perform the desired operation. Per or post-index of indirect address is possible. Special Function Register SFR The EU1010 includes some special function control registers in zero-page. For more detailed information about the special function registers, please refer to next section. Stack pointer register SP The stack pointer is an 8-bit register that is used to control the addressing of the variable-length stack. The stack pointer is automatically incremented and decremented under control of the microprocessor the perform stack manipulations under direction of either the program or interrupts. The stack allows a simple implementation of nested subroutines and multiple level interrupts. The stack pointer is initialized by the user’s software. Program counter PC The 14-bit program counter register provides the address that step the microprocessor through sequential program instructions. Program Flag Register P The 8-bit status flag register contains seven status flags. Some of the flags are controlled by the program and others may be controlled both by the program and the MCU. Instruction set contains a number of conditional branch instructions that are designed to allow testing of these flags. 3/21 |
