Pin may be either an input or output
Pins “must be” connected as described
Synchronous. Inputs must meet setup and hold times relative to PCLK2:1 for proper operation.
Outputs are synchronous to PCLK2:1.
Asynchronous. Inputs may be asynchronous to PCLK2:1.
While the bus is in the Hold Acknowledge or Bus Backoff state, the pin:
