LINSCI™ SERIAL COMMUNICATION INTERFACE (cont’d)
10.5.4 General Description
The interface is externally connected to another
device by two pins:
– TDO: Transmit Data Output. When the transmit-
– RDI: Receive Data Input is the serial data input.
Through these pins, serial data is transmitted and
received as characters comprising:
– An Idle Line prior to transmission or reception
– A start bit
– A data word (8 or 9 bits) least significant bit first
– A Stop bit indicating that the character is com-
This interface uses three types of baud rate gener-

ter is disabled, the output pin returns to its I/O
port configuration. When the transmitter is ena-
bled and nothing is to be transmitted, the TDO
pin is at high level.
Oversampling techniques are used for data re-
covery by discriminating between valid incoming
data and noise.
