PIC16F72X/PIC16LF72X
5.0
The PIC16F72X/PIC16LF72X
capability of storing eight 14-bit words in its data
latches. The data latches are internal to the
PIC16F72X/PIC16LF72X devices 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 Word command is used
to load a single data latch. The data latch will hold the
data until Begin Externally Timed Programming or
Begin Internally Timed Programming command is
given.

Advance Information
The data latches are aligned with the 3 LSb of the PC.
The address of the PC, at the time the Begin Externally
Timed Programming or Begin Internally Timed
Programming command is given, will determine which
location(s) in memory are written. Writes can not cross
a physical eight-word boundary.
attempting to write from PC 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 diagrams
show the recommended flowcharts for programming.
