Diagnostic interface 28/72

netRAPID Chip Carrier | Design Guide

5.2 Serial interface – UART

The pins of the UART interface are shared with the pins for the SYNC interface.

Note: The standard firmware activates the SYNC interface and deactivates the UART by

default.

The following pins of the netRAPID relate to the serial interface (UART). The table provides the

signal names:

Pin Name Shared with

42 UART_RX SYNC0

43 UART_TX SYNC1

Table 10: Pin assignment to serial interface (UART)

The signals UART_RX and UART_TX have LVTTL level. They allow setting up an interface for

diagnostic purposes.
