OPERATING MODE
3-State A bus and B bus (input A & B simultaneously)
B → A, transparent B latch, generate parity from B0 - B7, check B bus parity
B → A, transparent A & B latch, generate parity from B0 - B7, check A & B bus parity
B → A, B bus latched, generate parity from latched B0 - B7 data, check B bus parity
B → A, transparent B latch, parity feed-through, check B bus parity
B → A, transparent A & B latch, parity feed-through, check A & B bus parity
A → B, transparent A latch, generate parity from A0 - A7, check A bus parity
A → B, transparent A & B latch, generate parity from A0 - A7, check A & B bus parity
A → B, A bus latched, generate parity from latched A0 - A7 data, check A bus parity
A → B, transparent A latch, parity feed-through, check A bus parity
A → B, transparent A & B latch, parity feed-through, check A & B bus parity
Output to A bus and B bus (NOT ALLOWED)
