PROGRAMMING ALGORITHMS
The devices have the capability of storing eight 14-bit
words in its data latches. The data latches are internal
and are only used for programming. The data latches
allow the user to program up to eight program words
with a single Begin Externally Timed Programming or
Begin Internally Timed Programming command. The
Load Program Data or the Load Configuration com-
mand is used to load a single data latch. The data latch
will hold the data until the Begin Externally Timed Pro-
gramming or Begin Internally Timed Programming
command is given.
The data latches are aligned with the 3 LSb of the
address. The address at the time the Begin Externally
Timed Programming or Begin Internally Timed Pro-
gramming command is given will determine which loca-
tion(s) in memory are written. Writes cannot cross a
physical eight-word boundary. For example, attempting
to write from address 0002h-0009h will result in data
being written to 0008h-000Fh.
If more than 8 data latches are written without a Begin
Externally Timed Programming or Begin Internally
Timed Programming command the data in the data
latches will be overwritten. The following figures show
the recommended flowcharts for programming.
