BEGIN INTERNALLY TIMED PROGRAMMING

A Load Configuration or Load Data for Program Memory command must be given before every Begin Programming

command. Programming of the addressed memory will begin after this command is received. An internal timing

The End Externally Timed Programming command is not needed when the Begin Internally Timed Programming is used

to start the programming.

The program memory address that is being programmed is not erased prior to being programmed.

BEGIN EXTERNALLY TIMED PROGRAMMING

A Load Configuration or Load Data for Program Memory command must be given before every Begin Programming

command. Programming of the addressed memory will begin after this command is received. To complete the

programming the End Externally Timed Programming command must be sent in the specified time window defined by

Externally timed writes are not supported for Configuration and Calibration bits. Any externally timed write to the
