– Checks parity of received data byte

● Reduced power consumption mode

10.5.3 General description

The interface is externally connected to another device by two pins (see Figure 56):

● TDO: Transmit Data Output. When the transmitter and the receiver are disabled, the

output pin returns to its I/O port configuration. When the transmitter and/or the receiver

are enabled and nothing is to be transmitted, the TDO pin is at high level.

● RDI: Receive Data Input. This is the serial data input. Oversampling techniques are

used for data recovery by discriminating between valid incoming data and noise.

t(s) Through these pins, serial data is transmitted and received as frames comprising:

c ● an Idle Line prior to transmission or reception

du ● a start bit

ro ● a data word (8 or 9 bits) least significant bit first

P ● a Stop bit indicating that the frame is complete

te This interface uses two types of baud rate generator:

le ● a conventional type for commonly-used baud rates

so ● an extended type with a prescaler offering a very wide range of baud rates even with

Obsolete Product(s) - Ob non-standard oscillator frequencies
