Figure 22 - Serial Port Input and REOP, Output and TEOP
Note: The frequency of the clock input CKi is assumed to be at the output bit rate. However, it can be at twice the bit rate in the Internal Timing
Mode.
Timing is over recommended temperature & power supply voltages (VDD=5V±5%, VSS=0V, TA=–40 to 85°C).
Typical figures are at 25
°C and are for design aid only: not guaranteed and not subject to production testing.
