a The status bits become inactive in the state preceding t
b The data hold time lasts only until the interrupt acknowledge signal deasserts, even if the interrupt acknowledge
c This parameter applies to an interrupt acknowledge cycle that follows a write cycle.
d If followed by a write cycle, this change occurs in the state preceding that write cycle.
