A single write to either a volatile or non-volatile register. At address 00h bit 7 of ACR determines which memory type is being written.

Stop
Multiple writes are possible only if the starting address is 08h and it should be stopped with the first nonvolatile data byte. If
a nonvolatile write does not end with a STOP procedure the register is not written.
(B) Read data procedure with designated address.
1. Host transfers the start condition
2. Host transfers the device slave address with the write mode R/W bit (0)
3. ACK signal recognition from the device
4. Host transfers the read address
5. ACK signal recognition from the device
6. Host transfers the re-start condition
7. Host transfers the slave address with the read mode R/W bit (1).
8. ACK signal recognition from the device
9. The device transfers the read data from the designated address
10. Host transfers ACK signal
11. The (9) & (10) routines above are repeated if needed, and the read address is auto-incremented
12. Host transfers ACK ‘H’ to the device
13. Host transfers the stop condition

(C) Read data procedure without a designated address.
1. Host transfers the start condition
2. Host transfers the device slave address with the read mode R/W bit =1
3. ACK signal recognition from the device. (Host then changes to receiver)
4. The device transfers data from the previous access address +1
5. Host transfers ACK signal
6. The (4) & (5) routines above are repeated if needed
7. Host transfers ACK ‘H’
8. Host transfers the stop condition
