4.2 Memory Programming
The Programming procedure writes the user
program and data into the Flash Memory,
EEPROM and Option Bytes. The programming
procedures are entered by setting the V
equal to V
following pins are used in Programming mode:
During the device programming, the internal clock
is used, so the OSCin and OSCout pins don’t have
to be considered.
4.2.1 Programming Mode start. The
sequence starts the Programming Mode:

Write the currently addressed block with the 32 bytes
following the command. The Block locations are erased
before being written.
Write the byte addressed by the next data sent in the
currently addressed page.
Erase the block addressed by 3 MSB of the next data sent
and inside the currently addressed page.
Erase the byte addressed by the next data sent and inside
the currently addressed page.
Read the byte addressed by the next data sent and inside
the current page. The read data is sent by the device after
the re-send of the Slave Address with the R/W bit changed.
All the memory is erased.
Write the currently addressed block with the 32 bytes
following the command. The Block locations aren’t erased.
The currently addressed page is set with the next data sent.
Read the memory location currently addressed. The read
data is sent by the device after the command is
acknowledged. The current memory absolute address is
post-incremented.
The current block address is incremented modulo 8
(address 0 follows after address 7 and the Page is post-
incremented)
This command is followed by a status data byte. Mostly
used in error condition and to check if the device is locked
