Note 1: Applies to EXTCLK, SYNC_IN, SYNC_OUT, HW_IN, /RD, /WR, /CS, D15 to D0, /UBE,
/LBE, A3 to A1 pins.
Note 2: Applies to /RST_TE, 80/68, /WAKEUP, PDET, and VDSEL pins.
Note 3: IOH = -0.4 mA, IOL = 1.2 mA
Note 4: When HW_OUT pin is set to open drain. Condition: RL = 500 Ω
Note 5: When pins D15 to D0 are in the input condition (when word access (16 bits) is specified)
and when pins D7 to D0 are in the input condition (before issuing the SYSTEM–
CONFIGURATION–REQUEST command or when byte access is (8 bits) is specified).
b. When DVDD2 = 3.3 V ± 0.3 V (VDSEL pin = “L”, Top = 0 to 70 °C)
