I've got a TLC5923 wired up on a board to drive a couple of UV LEDs. I have multiple channels, all of which work except for channel zero. The wiring between channels is identical, The SPI mode I'm using (I believe) is correct, and I've adhered to all the AC timing characteristics called out in the data sheet (I'm communicating with the device at an extremely slow rate, so the nanosecond setup times that are required for everything are more than satisfied)
Has anyone had a similar experience with this chip? The behavior persists across several boards, so I don't think I've fried a channel. Not sure what's up here.
