Note:
Stresses above those listed as "absolute maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating conditions or extended periods may affect device reliability.


Description

The interface is externally connected to another device by two pins (see Figure 53):
  TDO: Transmit Data Output. When the transmitter is disabled, the output pin returns to its I/O port configuration.
      When the transmitter is enabled and nothing is to be transmitted, the TDO pin is at high level.
  RDI: Receive Data Input is the serial data input.
      Oversampling techniques are used for data recovery by discriminating between valid incoming data and noise.
      Through this pins, serial data is transmitted and received as frames 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 frame is complete.
This interface usestwo typesofbaud rate generator of the ST72314J:
  A conventional type for commonly-used baud rates,
  An extended type with a prescaler offering a very wide range of baud rates even with non-standard oscillator frequencies.
