I/O
I2C-bus or SPI interface select. I2C-bus interface
is selected if this pin is HIGH. SPI interface is
selected if this pin is LOW
RX

I
UART Receive Data or Infrared Receive Data.
UART receive data input must idle HIGH. Infrared
receive data input must idle LOW. If this pin is not
used, tie it to VCC or pull it high via a 100k ohm
resistor.
TX

6
O
UART Transmit Data or Infrared Encoder Data. In
the standard UART Transmit Data mode, the TX
signal will be HIGH during reset or idle (no data). In
the Infrared mode, the inactive state (no data) for
the Infrared encoder/decoder interface is LOW. If
ithis pin is not used, it should be left unconnected.

O
I2C-bus data input/output (open-drain). If SPI con-
figuration is selected, then this pin is undefined and
must be connected to VCC.

I
I2C-bus or SPI serial input clock.
When the I2C-bus interface is selected, the serial
clock idles HIGH. When the SPI interface is
selected, the serial clock idles LOW.

for Auto RTS Hardware Flow Control, Auto RS-485
Half-Duplex direction control or as a general pur-
pose output.
