(10) Extended I/O Serial Interface Timing
(VCC
= 2.7 V to 3.6 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
*1 : CL is the load capacitance applied to pins for testing.
*2 : tCP is internal operating clock cycle time. Refer to “ (1) Clock Timing”.
Notes :
The above rating is in CLK synchronous mode.
Values on this table are target values.
