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
ISL22313 responds with an ACK. At this time, the device
enters its standby state (see Figure 18).
The non-volatile write cycle starts after STOP condition is
determined and it requires up to 20ms delay for the next
non-volatile write. Thus, non-volatile registers must be
written individually.
Read Operation
A Read operation consist of a three byte instruction followed
by one or more Data Bytes (see Figure 19). 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 ISL22313 responds with an ACK. Then the ISL22313
transmits Data Bytes as long as the master responds with an
ACK during the SCL cycle following the eighth bit of each
byte. The Data Bytes are from the registers indicated by an
internal pointer. This pointer initial value is determined by the
Address Byte in the Read operation instruction, and
