LOW VOLTAGE DUART WITH POWERSAVE
5
OP2A#
-
32
O
Output Port 2 Channel A - The output state is defined by the user and
through the software setting of MCR[3]. INTA is set to the active mode
and OP2A# output to a logic 0 when MCR[3] is set to a logic 1. INTA is
set to the three state mode and OP2A# to a logic 1 when MCR[3] is set
to a logic 0. This output should not be used as a general output else it
will disturb the INTA output functionality. If it is not used at all, leave it
unconnected.
TXB
6
8
O
UART channel B Transmit Data. If it is not used, leave it unconnected.
RXB
3
4
I
UART channel B Receive Data. Normal receive data input must idle at
logic 1 condition. If it is not used, tie it to VCC or pull it high via a 100k
ohm resistor.
RTSB#
15
22
O
UART channel B Request-to-Send (active low) or general purpose out-
put. If it is not used, leave it unconnected.
CTSB#
16
23
I
UART channel B Clear-to-Send (active low) or general purpose input.
This input should be connected to VCC when not used.
DTRB#
-
35
O
UART channel B Data-Terminal-Ready (active low) or general purpose
output. If it is not used, leave it unconnected.
DSRB#
-
20
I
UART channel B Data-Set-Ready (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
CDB#
-
16
I
UART channel B Carrier-Detect (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
RIB#
-
21
I
UART channel B Ring-Indicator (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
OP2B#
-
9
O
Output Port 2 Channel B - The output state is defined by the user and
through the software setting of MCR[3]. INTB is set to the active mode
and OP2B# output to a logic 0 when MCR[3] is set to a logic 1. INTB is
set to the three state mode and OP2B# to a logic 1 when MCR[3] is set
to a logic 0. This output should not be used as a general output else it
will disturb the INTB output functionality. If it is not used, leave it uncon-
nected.
ANCILLARY SIGNALS
XTAL1

I
Crystal or external clock input.
XTAL2

14
O
Crystal or buffered clock output.
16/68#
17
24
I
Intel or Motorola Bus Select.
When 16/68# pin is at logic 1, 16 or Intel Mode, the device will operate
in the Intel bus type of interface.
When 16/68# pin is at logic 0, 68 or Motorola mode, the device will
operate in the Motorola bus type of interface.
