1. In order to prevent any incorrect operation while operating in the X2 Mode, users must be aware that all peripherals using
AT/T89C51CC02
the clock frequency as a time reference (UART, timers...) will have their time reference divided by 2. For example, a free run-
ning timer generating an interrupt every 20 ms will then generate an interrupt every 10 ms. A UART with a 4800 baud rate
will have a 9600 baud rate.
