QWhat baud rates can be achieved by the ADuC834? Can the ADuC834 achieve a baud
115200 baud when used with a standard 32.768kHz watch crystal. How is this
AThe ADuC834 can achieve baud rates up to 393kbaud. In terms of standard baud
rates the highest
baud rate obtainable by the ADuC834 is 230400 baud. Yes, the ADuC834 can
achieve a baud rate
of 115200 when used with a standard 32.768kHz watch crystal.
The ADuC834 includes a special baud rate timer that allows much more
flexibility as regards
achieving particular baud rates (see page 63 of the datasheet for more
details). There are two
advantages why one should configure the baud rate using the UartBaud generator.
1) To achieve particular standard baud rates up to and including 115200 and
2) To free up a timer. The user is free to use all 3 timers for timer functions
while the baud rate is
controlled via the UartBaud generator.
