4.2 Memory Programming
The Programming procedure writes the user
program
and data
into
EEPROM and Option Bytes. The programming
procedures are entered by setting the V

and releasing the Reset signal. The
following pins are used in Programming mode:

-
Yes
Write the currently addressed block with the 32 bytes
following the command. The Block locations are erased
before being written.
ByteWrite

2
-
Yes
Write the byte addressed by the next data sent in the
currently addressed page.
BlockErase
00000011
1
Yes
Erase the block addressed by the next data sent and inside
the currently addressed page.
ByteErase
00000100
1
Yes
Erase the byte addressed by the next data sent and inside
the currently addressed page.
ByteRead
00000101
1
1
-
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.
GlobalErase
00001001
-
-
Yes
All the memory is erased.
FastBlockWrite 00001011
32
-
No
Write the currently addressed block with the 32 bytes
following the command. The Block locations aren’t erased.
