STA323WQS

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 STA323WQS. 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 STA323WQS acknowledges this and then the master writes the internal address

byte. After receiving, the internal byte address the STA323WQS 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 STA323WQS acknowledges this and then

responds by sending one byte of data. The master then terminates the transfer by

generating a STOP condition.

Random address multi-byte read

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

then read from sequential addresses within the STA323WQS. The master acknowledges

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