Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain.
PwrSave

12
I
PowerSave (active high). This feature isolates the L2551’s data bus
interface from the host preventing other bus activities that cause higher
power drain during sleep mode. See Sleep Mode with Auto Wake-up
and PowerSave Feature section for details.
RESET

I
When 16/68# pin is at logic 1 for Intel bus interface, this input becomes
RESET (active high). When 16/68# pin is at logic 0 for Motorola bus
interface, this input becomes RESET# (active low).
A 40 ns minimum active pulse on this pin will reset the internal registers
and all outputs of channel A and B. The UART transmitter output will be
held at logic 1, the receiver input will be ignored and outputs are reset
during reset period (see UART Reset Conditions).
VCC

Pwr
2.25V to 5.5V power supply. All inputs are 5V tolerant.
GND

Pwr
Power supply common, ground.

No Connection. These pins are not connected internally. But if there is
a possibility of migrating to the XR16L2751 for future needs, please
refer to the XR16L2751 datasheet to determine if these pins should be
connected to VCC or GND.
