Error Correction
The ADM1064 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 ADM1064 is correct. The PEC
byte is an optional byte sent after that last data byte has been
written to or read from the ADM1064. The protocol is as
follows:
1.
The ADM1064 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 42.
