SERIAL INTERFACES
Application UART Interface
The Anthias UART interface provides a simple mechanism for communicating with other serial
devices using the RS232 protocol.
2 signals implement the UART function, UART_TX and UART_RX. When Anthias is connected to
another digital device, UART_RX and UART_TX transfer data between the 2 devices.
UART configuration parameters, e.g. baud rate and data format, are set using ANTHIAS
application code firmware.
When selected in firmware PIO[0] is assigned to a UART_TX output and PIO[1] is assigned to a
UART_RX input, see the module pad assignment and description for more details.
The UART CTS and UART RTS signals can be assigned to any PIO pad by the on-chip firmware.
Note: To communicate with the UART at its maximum data rate using a standard PC, the PC
requires an accelerated serial port adapter card.
