A similar procedure can be used to write a single

block:

1.

The

SetPage command is sent, followed by

the page number where the data should be

written

2.

The

IncBlock command is sent as many times

as the block number inside the page (for ex-

ample: to address the block 3 the

IncBlock

must be sent 3 times)

3.

The

WriteBlock command is sent followed by

the 32 data bytes to be written.

4.

After the 32th byte is sent, the device holds

the SCL line low until all the data are not

stored in the memory (about 4.5 ms: 2 ms for

erasing and 2.5 for writing: the same time for

a single byte)

The procedures described previously can be

repeated as many time as needed, without exiting

from Programming Mode or re-sending the Slave

Address again.

The commands ByteErase and BlockErase, used

instead of ByteWrite and BlockWrite, erase (put all

bit to 0) the specified memory location or block.

4.2.4 Option Bytes Programming. The

Option

Byte addresses cannot be accessed with a

sequential procedure like the one described in

Section

4.2.2.

Actually,

the

pointers

are

automatically incremented up to the last block or

address in page 31. A further increment sets all the

pointers to 0.

The Option Byte addresses (located at page 48,

block 0, addresses 0-7) must be accessed with a

direct addressing procedure as the one described

in Section 4.2.3.

If the Fast Programming procedure is used, it must

be followed by a Random Block Writing procedure

to program the Option Bytes. The other 24 bytes of

the block can be written with dummy values.
