EXAMPLE: READING FROM THE THS7303
The read operation consists of two phases. The first phase is the address phase, where an I2C master initiates a
write operation to the THS7303 by generating a start condition (S) followed by the THS7303 I2C address in MSB
first bit order, followed by a '0' to indicate a write cycle. After receiving acknowledges from the THS7303, the
master presents the sub-address (channel) of the register it wants to read. After the cycle is acknowledged (A),
the master terminates the cycle immediately by generating a stop condition (P).
The second phase is the data phase. In this phase, an I2C master initiates a read operation to the THS7303 by
generating a start condition followed by the THS7303 I2C address in MSB first bit order, followed by a '1' to
indicate a read cycle. After an acknowledge from the THS7303, the I2C master receives one byte of data from
the THS7303. After the data byte has been transferred from the THS7303 to the master, the master generates a
not acknowledge (A) followed by a stop. As with the write function, in order to read all channels, steps 1 through
11 must be repeated for each channel desired.
