Test Register
There are three test functions provided in the TLC34075, and they are all controlled and monitored through
the test register. They are data flow check, DAC analog test, and screen integrity test.
The test register has two ports: one for a control word, accessed by writing to the register location, and one
for the data word, accessed by reading from the register location. Depending on the channel written in the
control word, the data read presents the information for that channel.
The control word is three bits long and occupies D<2:0>. It specifies which of the eight channels to inspect.
The following table and state machine diagrams show how each channel is addressed:
