NOTES FOR DC ELECTRICAL CHARACTERISTICS
1.
The operating supply current is measured with all output disconnected;
XTAL1 driven with tr = tf = 5ns; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;
2.
The IDLE MODE supply current is measured with all output pins disconnected;
XTAL1 driven with tr = tf = 5ns; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;
3.
The POWER-DOWN MODE supply current is measured with all output pins disconnected;
VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;
4.
Port 1, 3 source a transition current when they are being externally driven from HIGH to LOW. The transition current reaches its
maximum value when VIN is approximately 2V.
5.
Under
steady state (non-transient) conditions, IOL must be externally
Limited as follows: Maximum IOL per port pin: 20mA
Maximum total IOL for all output pins: 80mA
