    9.1.1.6.2 Data Toggle
    Checking the Data Toggle bit on DQ6 (DQ14) is a method of determining whether a
    Program or Erase instruction is in progress or has completed. Figure 4 shows the Data
    Toggle algorithm.
    When the MCU issues a programming instruction, the embedded algorithm within the
    PSD4000 begins. The MCU then reads the location to be programmed in Flash to check
    status. Data bit DQ6 (DQ14) of this location will toggle each time the MCU reads this
    location until the embedded algorithm is complete. The MCU continues to read this
    location, checking DQ6 (DQ14) and monitoring the Error bit on DQ5 (DQ13) . When
    DQ6 (DQ14) stops toggling (two consecutive reads yield the same value), and the Error bit
    on DQ5 (DQ13) remains
    ‘
    0
    ’
    , then the embedded algorithm is complete. If the Error bit on
    DQ5 (DQ13) is
    ‘
    1
    ’
    , the MCU should test DQ6 (DQ14) again, since DQ6 (DQ14) may have
    changed simultaneously with DQ5 (DQ13) (see Figure 4).
    The Error bit at DQ5 (DQ13) will be set if either an internal timeout occurred while the
    embedded algorithm attempted to program, or if the MCU attempted to program a
    ‘
    1
    ’
    to a
    bit that was not erased (not erased is logic
    ‘
    0
    ’
    ).
