Read/Write Select – RDB_WR_A and RDB_WR_B - Read/Write Select – RDB_WR_A and RDB_WR_B - AM007

When this pin is 1, it selects the write operation. When it is 0, it selects the read operation. The polarity is invertible. Each port can only execute a read or write operation in one cycle. When a write operation executes, the read outputs hold the previous value.
