24.3.13 Measuring Conditions for AC Characteristics
Input reference levels High level: V_IH min. value, Low level: V_IL max. value
Output reference level High level: 2.0 V, Low level: 0.8 V
I_OL
LSI output pin
C_L
DUT output
V ^VREF
I_OH
C_Lis a total value that includes the measuring instrument capacitance.
The following C_L values are used:
30 pF: CK, CS3 to CS0, BREQ, BACK, AUDCK
50 pF: A21 to A0, D15 to D0, RD, WRH, WRL
100 pF: AUDATA3 to 0, AUDSYNC
30 pF: All other port output pins and supporting module output pins
I_OL and I_OH are the condition for the I_OL = 1.6 mA, I_OH = 200 µA.
