Answer / saili

the 8051 serial communication uses 11.059 MHz clock frqueny.
this is used to obtain a specific standardised bit rate for
serial communication. using 12MHz or 24MHz frequeny wont
yeild a proper standard bit rate in serial communication.

Answer / sunil h yadav

The maximum operating frequency=1/2*clock frequency.
The clock frequency of 8051 is 24MHz.As 8051 has two crystal pins,therefore max.operating frq.becomes 12MHz.But due to some
constraints max.frequency reduces to 11.059
