Description
Data Terminal Ready. When LOW, this informs the MODEM or
data set that the UART is ready to establish communication link.
The NDTR output signal can be set to an active LOW by
programming bit 0 (DTR) of the MODEM Control Register to
HIGH level. A Master Reset operation sets this signal to its
inactive (HIGH) state. Loop mode operation holds this signal in its
inactive state.
When LOW, this informs the MODEM or data set that the UART
is ready to exchange data. The NRTS output signal can be set to an
active LOW by programming bit 1 (RTS) of the MODEM Control
Register. A Master Reset operation sets this signal to its inactive
(HIGH) state. Loop mode operation holds this signal in its inactive
state.
Serial Output. Composite serial data output to the communications
link (peripheral, MODEM or data set). The SOUT signal is set to
the Marking (logic 1) state upon a Master Reset operation.
