Other Parts Discussed in Thread: DLPA2000,
On initial power-up, we apply VSYS (3.8V) and then VCC (1.8V). Before PROJ_ON pin is toggled, i noticed that the I2C0_SCL and I2C_SDA pins are pulled low. These pins stay in this state until PROJ_ON turns on the DLPA2000. After that, the I2C lines go High-Z. After that, we can clear PROJ_ON and the SDA and SCL lines remain High-Z.
Is this behavior expected? It seems strange that the I2C bus does not power up to High-Z by default.
Thanks,
Gerald
