    NOTES
    NOTES ON PROGRAMMING
    1. Processor Status Register
    (1) Initializing of processor status register
    Flags which affect program execution must be initialized after a reset.
    In particular, it is essential to initialize the T and D flags because
    they have an important effect on calculations. Initialize these
    flags at beginning of the program.
    <Reason>
    After a reset, the contents of the processor status register (PS) are
    undefined except for the I flag which is “1”.
    Fig 73. Initialization of processor status register
    (2) How to reference the processor status register
    To reference the contents of the processor status register (PS),
    execute the PHP instruction once then read the contents of (S+1).
    If necessary, execute the PLP instruction to return the PS to its
    original status.
    Fig 74. Stack memory contents after PHP instruction
    execution
    2. Decimal calculations
    (1) Execution of decimal calculations
    The ADC and SBC are the only instructions which will yield
    proper decimal notation, set the decimal mode flag (D) to “1”
    with the SED instruction. After executing the ADC or SBC
    instruction, execute another instruction before executing the
    SEC, CLC, or CLD instruction.
    Fig 75. Execution of decimal calculations
    (2) Notes on status flag in decimal mode
    When decimal mode is selected, the values of three of the flags in
    the status register (the N, V, and Z flags) are invalid after a ADC
    or SBC instruction is executed.
    The carry flag (C) is set to “1” if a carry is generated as a result of the
    calculation, or is cleared to “0” if a borrow is generated. To
    determine whether a calculation has generated a carry, the C flag
    must be initialized to “0” before each calculation. To check for a
    borrow, the C flag must be initialized to “1” before each calculation.
    3. JMP instruction
    When using the JMP instruction in indirect addressing mode, do
    not specify the last address on a page as an indirect address.
    4. Multiplication and Division Instructions
     The index X mode (T) and the decimal mode (D) flags do not
    affect the MUL and DIV instruction.
     The execution of these instructions does not change the
    contents of the processor status register.
    5. Read-Modify-Write Instruction
    Do not execute any read-modify-write instruction to the read
    invalid (address) SFR.
    The read-modify-write instruction reads 1-byte of data from
    memory, modifies the data, and writes 1-byte the data to the
    original memory.
    In the 740 Family, the read-modify-write instructions are the
    following:
    (1) Bit handling instructions:
    CLB, SEB
    (2) Shift and rotate instructions:
    ASL, LSR, ROL, ROR, RRF
    (3) Add and subtract instructions:
    DEC, INC
    (4) Logical operation instructions (1’s complement):
    COM
    Although not the read-modify-write instructions, add and
    subtract/logical operation instructions (ADC, SBC, AND, EOR,
    and ORA) when T flag = “1” operate in the way as the read-
    modify-write instruction. Do not execute them to the read invalid
    SFR.
    <Reason>
    When the read-modify-write instruction is executed to the read
    invalid SFR, the following may result:
    As reading is invalid, the read value is undefined. The instruction
    modifies this undefined value and writes it back, so the written
    value will be indeterminate.
