STA323W

I2C bus specification

35/77

Current address multi-byte read

The multi-byte read modes can start from any internal address. Sequential data bytes are

read from sequential addresses within the STA323W. The master acknowledges each data

byte read and then generates a STOP condition to terminate the transfer.

Random address byte read

Following the START condition the master sends a device select code with the RW bit set

to 0. The STA323W acknowledges this and then the master writes the internal address byte.

After receiving, the internal byte address the STA323W again responds with an

acknowledgement. The master then initiates another START condition and sends the device

select code with the RW bit set to 1. The STA323W acknowledges this and then responds

by sending one byte of data. The master then terminates the transfer by generating a STOP

condition.
