TEST CONDITIONS
VDD = 4.5V, IOH = -400 μA
VDD = 2.4V, IOH = -200 μA
VDD = 4.5V, Vin = 2.4V
VDD = 2.4V, Vin = 1.4V
VDD = 4.5V, Vin = 2.4V
VDD = 2.4V, Vin = 1.4V
Notes:
*1. RST pin is a Schmitt trigger input.
*2. P0, ALE and /PSEN are tested in the external access mode.
*3. XTAL1 is a CMOS input.
*4. Pins of P1, P2, P3, P4 can source a transition current when they are being externally driven from 1 to 0.
