A Load Configuration, Load Data for Program Memory
or Load Data for Data Memory command must be given
before every Begin Programming command. Program-
ming 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
T
EEPROM, therefore, the device should be erased prior
to executing this command (see
FIGURE 4-9:
4.3.10
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
