NOTES:
1. If a start bit occurs at a time less than t
DC
before a high-to-low transition of the clock, the start bit may not be recognized until the next
high-to-low transition of the clock. The start bit may be completely asynchronous with the clock.
2. Read is the overlap of CS1, CS3, RD/WR = 1 and CS2 = 0. If a pending DA has not been cleared by a read of the Receiver Holding
3. OE and PE share terminal 15 and are also available as two separate bits in the status register.
