The master sends the data and each byte isacknowledged by the I
terminates the transfer by generating a STOP (P) condition.
The sub-address decides the starting byte. A Multi-byte with sub-address 00H and 5
DATA_IN bytes would affect the bytes starting from DATA_OUT [119:112] to DATA_OUT
[87:80] and so on. A Multi byte with sub-address from the ranges 00H - 0FH produces illegal
sub-address signal to go high, and DATA_OUT[119:0] will not change until a successive
write operation request, with the correct range for sub-address will be made.
Read operation
Current byte address read
For the I
address read mode, following a START condition, the master sends the device address with
the RW bit set to 1. The I
the internal byte address counter. The master does not acknowledge the received byte, but
terminates the transfer with a STOP condition.
This method operation is not used.
