That's why you need a trick to connect the 6522 to a C64. OK, but in the context of reading from a device: you have a rising edge of PHI2, and you know that the address is valid on the bus. If I am a device, I should now post the data immediately on the bus, so the CPU can get it on the falling edge, right?
