General purpose I/O extended functionality
RS485 interface
The S215 register allows enabling the management of the control lines (/RE
and DE lines) of most RS485 buffer. The following figures illustrate the
RS485 wiring and the configuration required for activating the DE and /RE
management. Even one line is sufficient, for more flexibility two different
lines could managed the DE and RE RS485 control lines. Hereafter a
connection example with both lines or one line only.
