UART
The MPX-LX2160A module provides a maximum of 2 UARTs which can be
configured in two ways:
■
Two UARTs w/ hardware handshake signals
-or-
■
Four UARTs w/o hardware handshake signals (RX/TX only)
Configuration is done by software via RCW.
The following table shows the internal connections for two UARTs:
