Hi,
We use three TLC59116 on an I2C bus. It all works flawlessly. In between, however, the two registers 0 and 1 are sporadic adjusted, so that it looks as if the TLC59116 no longer works.
For an normal function register 0 should always be 0x80 and register 1 always 0x00. But in between these two registers are adjusted. Register 0 adjusted to 0x91 (Oscillator off) and register 1 pretends to 0x20.
When it occurs we are doing an sending nothing.
What cause could that be?
Thanks for a helpful answer
Andreas
