What is the bandwidth in MB/s of a parallel data link that consists of 32 wires for data transfer, a clock speed of 8 MHz, and data transfer every second rising clock edge?

2.

Assume a PIC18 with an FOSC of 40 MHz, and PORTB for data transfer. Suppose you want to transfer 256 bytes of data to an external device. How long does it take to transfer this data, using the code in this problem? Express this transfer rate in MB/s.
