2.4.3
The Load Configuration command advances the PC to
the start of configuration memory (0x2000-0x200F),
and loads the data for the first ID location. Once it is set
to the configuration region, only exiting and re-entering
Program/Verify mode will reset PC to the user memory
space.
FIGURE 2-6:
2.4.4
Begin programming only cycle programs the previously
loaded word into the appropriate memory (User
Program, Data or Configuration memory). A Load
command must be given before every Program-
ming command. Programming begins after this
command is received and decoded. An internal timing
mechanism executes the write. The user must allow for
program cycle time before issuing the next command.
No “End Programming” command is required.
The device must be Bulk Erased before starting a
series of programming only cycles.
