Serial port B,
MEI interface
C h a p t e r 2
The serial (UART) port B connector, X6, is a DSUB9 male connector. This
asynchronous serial port is DTE and requires a null-modem cable to connect to a
computer serial port.
The serial port B MEI (Multiple Electrical Interface) interface corresponds to NS9215
UART port B. The line drivers are configured using switch S1.
Note that all pins on S1 contribute to the line driver settings for this port.
Serial port B pins are allocated as shown:
By default, Serial B signals are configured to their respective GPIO signals.
It is the responsibility of the driver to configure them properly.
