Serial I/OThe W77E58 has two enhanced serial ports that are functionally similar to the serial port of the original8052 family. However the serial ports on the W77E58 can operate in different modes in order to obtaintiming similarity as well. Note that the serial port 0 can use Timer 1 or 2 as baud rate generator,but the serial port 1 can only use Timer 1 as baud rate generator. The serial ports have theenhanced features of Automatic Address recognition and Frame Error detection.
