31.3.17 AC Characteristics Measurement Conditions
• Input signal reference levels: high level = V_IH min, low level = V_IL max
• Output signal reference level: PVCC/2 (PVCC = 3.0 to 3.6 V)
• Input pulse level: PVSS to 3.0 V (where RES, MRES, NMI, MD1, MD0, MD_CLK1,
MD_CLK0, ASEMD, UDTRST, and Schmitt trigger input pins are within PVSS to PVCC)
• Input rise and fall times: 1 ns

CMOS output
Note: C_L is the total value that includes the capacitance of
measurement tools.
Each pin is set as follows:
30 pF: CKIO, SDRAS, SDCAS, CS0 to CS6,
SDCS0, SDCS1, SDCKE, SDWE, DQM0 to DQM3
50 pF: All other pins
