I
Clock Pre-scaler select. Connect to VCC for divide by 1
(default) and GND for divide by 4. MCR[7] can override
the state of this pin following reset or initialization. See
Figure 6 and MCR[7].

I
Transmit/Receive data sampling rate. Connect to VCC for
normal 16X sampling clock (standard baud rates, default)
or GND for 8X sampling clock to double the standard
baud rates, 2X.
RESET
35
39
36
I
Reset (active high) - A longer than 40 ns logic 1 pulse on
this pin will reset the internal registers and all outputs.
The UART transmitter output will be held at logic 1, the
receiver input will be ignored and outputs are reset during
reset period (see External Reset Conditions).
VCC

Pwr
3.3V or 5V power supply. Please note that the inputs are
not 5V tolerant when operating at 3.3V.
GND

17
Pwr
Power supply common, ground.
N.C.

No Connection. These pins are open, but typically, should
be connected to GND for good design practice.
