(4) UART1 to UART3
(VCC = 2.7 V to 3.6 V, AVCC
= 2.7 V to 3.6 V, VSS = AVSS = 0.0 V, TA = −40 °C to +85 °C)
Notes :
• These are AC ratings in the CLK synchronous mode.
• CL is the load capacitance value connected to pins while testing.
• tCP is the internal operating clock cycle time. Refer to “(1) Clock Timings” rating for tCP.
