Error Correction
The ADM1066 provides the option of issuing a PEC (packet
error correction) byte after a write to RAM, a write to EEPROM,
a block write to RAM/EEPROM, or a block read from RAM/
EEPROM. This enables the user to verify that the data received
by or sent from the ADM1066 is correct. The PEC byte is an
optional byte sent after that last data byte has been written to or
read from the ADM1066. The protocol is as follows:
1.
The ADM1066 issues a PEC byte to the master. The master
checks the PEC byte and issues another block read, if the
PEC byte is incorrect.
2.
A no acknowledge (NACK) is generated after the PEC byte
to signal the end of the read.
Note that the PEC byte is calculated using CRC-8. The frame
check sequence (FCS) conforms to CRC-8 by the polynomial

See the SMBus 1.1 specification for details.
An example of a block read with the optional PEC byte is
shown in Figure 47.
