3 0 AC Electrical Characteristics
Note 1 This delay will be lengthened by 1 character time minus the last stop bit time if the transmitter interrupt delay circuit is active (See FIFO Interrupt Mode
Operation)
Note 2 These specifications are preliminary
4 0 Timing Waveforms
Note 1 The 2 4V and 0 4V levels are the voltages that the inputs are driven to during AC testing
Note 2 The 2 0V and 0 8V levels are the voltages at which the timing tests are made
