I²C Bus
The I²C bus is implemented through the congatec Board Controller and accessed through the congatec CGOS driver and API. The controller
provides a fast-mode multi-master I²C bus that has the maximum I²C bandwidth.

GPIOs
The conga-TS570 offers General Purpose Input/Output signals on the A–B connector. The GPIO signals are controlled by the congatec Board
controller.
5.1.12
General Purpose Serial Interface
The conga-TS570 offers two standard 16C550 UARTs on the A–B connector via the congatec Board Controller. The interfaces support up to
115200 baud rate.
Note
The UART interfaces do not support hardware handshake and flow control.
5.1.13
Power Control
PWR_OK
Power OK from main power supply or carrier board voltage regulator circuitry. A high value indicates that the power is good and the module
can start its onboard power sequencing.
Carrier board hardware must drive this signal low until all power rails and clocks are stable. Releasing PWR_OK too early or not driving it low
at all can cause numerous boot up problems. It is a good design practice to delay the PWR_OK signal a little (typically 100ms) after all carrier
board power rails are up, to ensure a stable system.
A sample screenshot is shown below.
