The Write Buffer Programming Sequence will be Aborted under the following conditions:
When any of the conditions that cause an abort of write buffer command occur the abort will happen after the
Program Buffer to Flash command is issued, and will indicate a Program Fail in the Status Register at bit
location 4 (PSB). The next successful program operation will clear the failure status or a “Clear Status
Register” may be issued to clear the PSB status bit.
The Write Buffer Programming Sequence can be stopped and reset by the following: Hardware Reset or
Power cycle. However, using either of these methods may leave the area being programmed in an
intermediate state with invalid or unstable data values. In this case the same area will need to be
reprogrammed with the same data or erased to ensure data values are properly programmed or erased.
Page Programming should be done only once in any particular page before the sector in which the page
resides is erased. Page Programming more than once in the same page between erase operations will not
cause the operation to fail but may degrade the reliability of data in any Cache Line where data is changed,
until the next erase of the related sector.
Load a Word Count value that would cause the write buffer load sequence to attempt loading words past
the end of the aligned 512 byte page. Note that only the lower eight bits of the Word Count data value are
captured so no value > 255 can be recognized.
Write an address that is outside the Page of the Starting Address during the write buffer data loading stage
of the operation. Or, have a sector address not matching the one used in the initial command cycle of the
page programming operation.
The sector to be programmed is locked
