pin has no effect on the UARTs transmit or receive opera-
tion.
-RI A-B
39,23
43,26
41,21
I
Ring Indicator (active low) - These inputs are associated
with individual UART channels, A through B. 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.
-RTS A-B
32,24
36,27
33,22
O
Request to Send (active low) - These outputs are associated
with individual UART channels, A through B. A logic 0 on the
-RTS pin indicates the transmitter has data ready and
waiting to send. Writing a logic 1 in the modem control
register (MCR bit-1) will set this pin to a logic 0 indicating
data is available. After a reset this pin will be set to a logic
1. This pin has no effect on the UARTs transmit or receive
operation.
RX A-B
10,9
11,10
5,4
I
Receive Data (A-B) - These inputs are associated with
individual serial channel data to the 2550 receive input
circuits, A-B. The RX signal will be a logic 1 during reset, idle
(no data), or when the transmitter is disabled. During the
local loop-back mode, the RX input pin is disabled and TX
data is connected to the UART RX Input, internally.
TX A-B
11,12
13,14
7,8
O
Transmit Data (A-B) - These outputs are associated with
individual serial transmit channel data from the 2550. The
TX signal will be a logic 1 during reset, idle (no data), or when
the transmitter is disabled. During the local loop-back
mode, the TX output pin is disabled and TX data is internally
connected to the UART RX Input.
