(10) UART0 (SCI), UART1 (SCI) Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
* : For tCP (internal operating clock cycle time), refer to “(3) Clock Timings.”
Notes :
These are AC ratings in the CLK synchronous mode.
CL is the load capacitance value connected to pins while testing.
