Summary0002061: I2C pins are actively driven instead of open drain
DescriptionCustomer reports that I2C on NetDCUA5, pins 10+11 does not work. An oscilloscope diagram shows a half level signal on the ACK bit. Here the ACK (low) of the external hardware seems to run against the actively driven high bit of the Vybrid MCU.
Additional InformationThe generic configuration of I2C pins is broken as it does not use open drain pins. We have to fix this.
