Possibility of high frequency interrupt handle with MCF5223x

Dear all,

I want to use MCF5223x to read a 8bit digital signal and forward the sample
data to UDP packet.
The signal consists of 8bit data and 1 clock, data fetch at rising edge or
falling edge. However, the clock frequency is pretty high, max frequency is
about 12MHz.
Are there possible to use the CLOCK input to trigger an interrupt and sample
the data in each interrupt?

I want to do the connection as below:
CLOCK             ===>  nIRQ1
DATA[8:0]         ===>  PORT AN

So the system would include 3 tasks:
1. Interrupt for data input, interrupt trigger at about 12MHz
2. UDP Packet forwarding, each packet contains 200 samples
3. HTTP or TCP service for system configuration

Can a 60MHz ColdFireV2, 5223x, capable to do it?


B.R.
David
