    Notes:
    (5) t
    WC
    is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum
    time the device requires to automatically complete the internal write operation.
    (6) t
    WPH
    is the normal page write operation
    WE
    recovery time. t
    WPH2
    is the
    WE
    recovery time needed only after the end of issuing
    the three-byte SDP command sequence and before writing the first byte of data to the array. Refer to Figure 6 which illustrates
    the t
    WPH2
    requirement.
    (7) For faster t
    WC
    and t
    BLC
    times, refer to X28HC64.
