Write Operation

A Write operation requires a START condition, followed by a

valid Identification Byte, a valid Address Byte, a Data Byte,

and a STOP condition. After each of the three bytes, the

ISL22319 responds with an ACK. At this time, the device

enters its standby state (See Figure 14).

The non-volatile write cycle starts after STOP condition is

determined and it requires up to 20ms delay for the next

non-volatile write.

Read Operation

A Read operation consists of a three byte instruction

followed by one or more Data Bytes (See Figure 15). The

master initiates the operation issuing the following

sequence: a START, the Identification byte with the R/W bit

set to “0”, an Address Byte, a second START, and a second

Identification byte with the R/W bit set to “1”. After each of

the three bytes, the ISL22319 responds with an ACK. Then

the ISL22319 transmits Data Bytes as long as the master

responds with an ACK during the SCL cycle following the

eighth bit of each byte. The master terminates the read

operation (issuing a ACK and STOP condition) following the

last bit of the last Data Byte (See Figure 15).

In order to read back the non-volatile IVR, it is recommended

that the application reads the ACR first to verify the WIP bit

is 0. If the WIP bit (ACR[5]) is not 0, the host should repeat

its reading sequence again.
