THS8083T Datasheet, PDF (26/61 Pages) Texas Instruments – Triple 8-Bit, 80 MSPS, 3.3-V Video and Graphics Digitizer With Digital PLL

3.1.2 Read Format
First write the subaddress, where data needs to be read out, to THS8083 in the format as follows:
S
Slave address(w)
A
Subaddress
AP
Then:
S
Slave address(r)
A DataN AM Data(N+1) AM
……
NAM P
S
Slave address(r)
A
AM
Start condition
01000001 (0x41) if I2CA=0 / 01000011 (0x43) if I2CA=1
Acknowledge, it is generated by THS8083; if the transmission is successful, then A = 0, else
A=1
Acknowledge, it is generated by a master
NAM
Not acknowledge, it is generated by a master
Subaddress
Data0
Data(N–1)
P
Subaddress of the first register to read, length = one byte
First byte of the data read
Nth byte of the data read
Stop condition
In both write and read operations, the subaddress will be incremented automatically when multiple bytes are
written/read. So, only the first subaddress needs to be supplied to the THS8083.
R/W registers can be written and read.
R registers are read-only.
