Note 2: In the FIFO mode (FCR0 1) the trigger level interrupts, the receiver data available indication, the active RXRDY indication and the overrun error indication  
will be delayed 3 RCLKs. Status indicators (PE, FE, BI) will be delayed 3 RCLKs after the first byte has been received. For subsequently received bytes these  
indicators will be updated immediately after RDRBR goes inactive. Timeout interrupt is delayed 8 RCLKs.  
Note 3: Charge and discharge time is determined by V , V  
OL OH  
and the external loading.  
Note 4: These specifications are preliminary.
