12-Channel/8-Channel, Flash-Configurable System
Managers with Nonvolatile Fault Registers
The block write protocol (see Figure 11) allows the mas-
ter device to write a block of data (1 byte to 16 bytes) to
memory. Preload the destination address by a previous
send byte command; otherwise the block write com-
mand begins to write at the current address pointer.
After the last byte is written, the address pointer remains
preset to the next valid address. If the number of bytes
to be written causes the address pointer to exceed 8Fh
for configuration registers or configuration flash or FFh
for user flash, the address pointer stays at 8Fh or FFh,
respectively, overwriting this memory address with the
remaining bytes of data. The slave generates a NACK at
step 5 if the command code is invalid or if the device is
busy, and the address pointer is not altered.

The master sends a START condition.
The master sends the 7-bit slave address and a
write bit (low).
The addressed slave asserts an ACK on SDA.
The master sends the 8-bit command code for block
write (A5h).
The addressed slave asserts an ACK on SDA.
The master sends the 8-bit byte count (1 byte to 16
bytes), n.
The addressed slave asserts an ACK on SDA.
The master sends 8 bits of data.
The addressed slave asserts an ACK on SDA.
When PEC is enabled, the Block Write protocol
becomes:
The master sends a START condition.
The master sends the 7-bit slave ID plus a write
bit (low).
The addressed slave asserts an ACK on the data line.
The master sends 8 bits of the block write com-
mand code.
The slave asserts an ACK on the data line.
The master sends an 8-bit byte count (min 1, max
16), n.
The slave asserts an ACK on the data line.
The master sends 8 bits of data.

13) The master generates a STOP condition.
The block read protocol (see Figure 11) allows the
master device to read a block of up to 16 bytes from
memory. Read fewer than 16 bytes of data by issuing
an early STOP condition from the master, or by generat-
ing a NACK with the master. The destination address
should be preloaded by a previous send byte command;
otherwise the block read command begins to read at
the current address pointer. If the number of bytes to
be read causes the address pointer to exceed 8Fh for
the configuration register or configuration flash or FFh
in user flash, the address pointer stays at 8Fh or FFh,
respectively. The block read procedure is the following:
1) The master sends a START condition.
2) The master sends the 7-bit slave address and a write
