Consider the following assignments. Given that the bus clock (Fe) is 8 MHz, first produce SBR then calculate the BaudRate
SCIBDH = 0x12;
SCIBDL = 0x34;
Answer :- The SBR value is of 13-bit made from SCIBDH:SCIBDL. Thus SBR = 0x1234. In decimal it is 4660.
Now the baud rate is given by-

2) (10 points) Consider a microprocessor driven by an 8-MHz input clock, with a 16-bit external data bus. Assume that this microprocessor has a bus cycle whose minimum duration equals 4 input clock cycles. A bus cycle is the number of clock cycles required to accomplish a task (such as data transfer). What is the maximum data transfer rate across the bus that this microprocessor can sustain, in bytes?
