4.2.7
A Load Configuration or Load Data for Program
Memory command must be given before every Begin
Programming
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 T
program memory address that is being programmed is
not erased prior to being programmed.
The Begin Externally Timed Programming command
cannot be used for programming the Configuration
Words (see
FIGURE 4-7:
4.2.8
This command is required after a Begin Externally
Timed
command must be sent within the time window
specified by T
Programming command is sent.
After sending the End Externally Timed Programming
command, an additional delay (T
sending the next command. This delay is longer than
the delay ordinarily required between other commands
