TCS3404, TCS3414 − Principles of Operation
When an I2C Write or I2C Read (Combined Format) is initiated,
the byte count is also ignored but follows the SMBus protocol
specification. Data bytes continue to be transferred from the
TCS3414 (I2C) device to Master until a NACK is sent by the
Master.
The data formats supported by the TCS3404 and TCS3414
devices are:
• Master transmitter transmits to slave receiver
(SMBus and I2C):
• The transfer direction in this case is not changed.
• Master reads slave immediately after the first byte
(SMBus only):
• At the moment of the first acknowledgment
(provided by the slave receiver) the master
transmitter becomes a master receiver and the slave
receiver becomes a slave transmitter.
• Combined format (SMBus and I2C):
• During a change of direction within a transfer, the
master repeats both a START condition and the slave
address but with the R/W bit reversed. In this case, the
master receiver terminates the transfer by generating
a NACK on the last byte of the transfer and a STOP
condition.
