System Bus Clock and processor Clocking
The BCLKn and BCLKp inputs control the operating frequency of the processor system
bus interface. All processor system bus timing parameters are specified with respect to
the falling edge of BCLKn and rising edge of BCLKp. The address pins A[21:17]# will be
used to specify the system bus frequency during reset. The processor will ensure that
the correct bus/core ratio is elected based on the bus frequency that is specified during
reset.
