4.3.1
The Load Configuration command is used to access
the
Configuration Words, Calibration Words). The Load
Configuration command sets the address to 8000h and
loads the data latches with one word of data (see
Figure
After issuing the Load Configuration command, use the
Increment Address command until the proper address
to be programmed is reached. The address is then pro-
grammed by issuing either the Begin Internally Timed
Programming or Begin Externally Timed Programming
command.

4.3.2
The Load Data for Program Memory command is used to
load one 14-bit word into the data latches. The word
programs into program memory after the Begin Internally
Timed Programming or Begin Externally Timed
Programming command is issued (see

The only way to get back to the program memory
(address 0) is to exit Program/Verify mode or issue the
Reset Address command after the configuration memory
has been accessed by the Load Configuration command.

Externally timed writes are not supported
for Configuration and Calibration bits. Any
externally timed write to the Configuration
or Calibration Word will have no effect on
the targeted word.
