//Reads can occur on the rising edge I guess.
//so basically cpu clock goes high when cs goes high we go into a priming state
//where we wait until cs goes low. when cpu clock is low, do the actual write.
//in terms of the existing state, the access state needs to only do something
//if selected AND cpu_clock is low. If cpu clock is high, we should be in wait,
//and after the read/write is complete we should also go back to wait.
//actually that may only apply to writes, since reads should occur at the rising
//edge of i_cpuclk
//Starts out in state 0 with cpuclk low and cs high.
//Then, cpuclk goes high. This is now a valid time to read
//After this, cpuclk goes low again, this is now a valid time to write.
//so basically if cpuclk goes low when cs is low, go to wait state
//what I am thinking is basically 2 states like before. wait and access.
//we go to access when cpuclk is high and cs is high.
//we can read as soon as we want if rwn is high.
