I/O
Data bus (bidirectional). These pins are the 8-bit, 3-state data bus for
transferring information to or from the controlling CPU. D0 is the least
significant bit and the first data bit in a transmit or receive serial data stream.

When 16/68 pin is at logic 1 or unconnected, this output becomes active HIGH
interrupt output. The output state is defined by the user through the software
setting of MCR[5]. INT is set to the active mode when MCR[5] is set to a
logic 1. INT is set to the open-source mode when MCR[5] is set to a logic 0.
When 16/68 pin is at logic 0, this output becomes device interrupt output
(active LOW, open-drain). An external pull-up resistor to VDD is required.

O
Interrupt output (active HIGH). The output state is defined by the user
through the software setting of MCR[5]. INT is set to the active mode when
MCR[5] is set to a logic 1. INT is set to the open-source mode when MCR[5] is
set to a logic 0.
IOR
(VDD)

I
When 16/68 pin is at logic 1, this input becomes the read strobe (active LOW).
When 16/68 pin is at logic 0, this input pin is not used and should be
connected to VDD.
IOR

I
Read strobe (active LOW).
IOW

I
When 16/68 pin is at logic 1 or unconnected, this input becomes the write
strobe (active LOW).
When 16/68 pin is at logic 0, this input becomes read strobe when it is at logic
HIGH, and write strobe when it is at logic LOW.
IOW

I
Write strobe (active LOW).
LOWPWR

I
Low Power. When asserted (active HIGH), the device immediately goes into
low power mode. The oscillator is shut-off and some host interface pins are
isolated from the host’s bus to reduce power consumption. The device only
returns to normal mode when the LOWPWR pin is de-asserted. On the
negative edge of a de-asserting LOWPWR signal, the device is automatically
reset and all registers return to their default reset states. This pin has a 22 k

internal pull-down resistor, therefore, it can be left unconnected (refer to
RESET

I
Master Reset. When 16/68 pin is at logic 1 or unconnected, this input
becomes the RESET pin (active HIGH).
When 16/68 pin is at logic LOW, this input pin becomes RESET (active LOW).

I
Reset input (active HIGH). See Section 7.23 “SC16C850 external reset
condition and software reset” for initialization details.
RI
F3
27
I
Ring Indicator (active LOW). A logic 0 on this pin indicates the modem has
received a ringing signal from the telephone line. A logic 1 transition on this
input pin will generate an interrupt if modem status interrupt is enabled. Status
can be tested by reading MCR[6].
