(5) UART (SCI) Timings
(AVCC
= VCC = 5.0 V ± 10%, AVSS = VSS = DVSS = 0.0 V, Ta = 40 °C to +85 °C)
* : See “ (3) Clock Timings” for more information about tCP (internal operating clock cycle time) .
Notes :
These are the AC ratings for CLK synchronous mode.
CL is the load capacitor connected to the pin for testing.
