Timing is over recommended temperature & power supply voltages (V
=5V
±
5%, V
=0V, T
=–40 to 85
°
C).
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
Figure 23 - Serial Port Inputs and Outputs in External Timing Mode
Note
: The frequency of the clock input (CKi) should be at the output bit rate in the External Timing Mode.
