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).
4.0 Timing Waveforms
All timings are referenced to valid 0 and valid 1
External Clock Input (24 MHz Max)
TL/C/9426–2
AC Test Points
