Table 4-24 UART w/ hardware handshake: pin assignments
UART1 is the serial console of the MPX-LX2160A module but it can be configured for
GPIO as well. This setup may require hardware modifications which are not covered
by standard module versions. For more information on configuration and ordering
please contact MicroSys.
The following tables list the pin sharing options for UART1 and UART2:
