Read Format
First write the subaddress, where data needs to be read out, to the THS8083A in the following format:
S
Slave address(w)
A
Subaddress
A
P
Then:
S
Slave address(r)
A
DataN
AM
Data(N+1)
AM
……
NAM
P
S
Start condition
Slave address(r)
01000001 (0x41) if I2CA=0 / 01000011 (0x43) if I2CA=1
A
Acknowledge, generated by the THS8083A. If transmission is successful, then A = 0,
else A = 1.
AM
Acknowledge, generated by a master
NAM
Not acknowledge, generated by a master
Subaddress
Subaddress of the first register to read, length = one byte
Data0
First byte of the data read
Data(N1)
Nth byte of the data read
P
Stop condition
In both write and read operations, the subaddress is incremented automatically when multiple bytes are written/read.
So, only the first subaddress needs to be supplied to the THS8083A.
R/W registers can be written and read.
R registers are read-only.
