3. Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum IOL per port pin: 10 mA
Maximum IOL per 8-bit port:
Ports 1, 2 and 3: 15 mA
Maximum total IOL for all output pins: 71 mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test conditions.
4. Power-down ICC is measured with all output pins disconnected; XTAL2 NC.; RST = VSS (See Figure 47.).
5. Idle ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns, VIL = VSS + 0.5V, VIH = VCC
0.5V; XTAL2 N.C; RST = VSS (See Figure 46.).

6. Operating ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (See Figure 48.), VIL
=
VSS + 0.5V, VIH = VCC - 0.5V; XTAL2 N.C.; RST = VCC. ICC would be slightly higher if a crystal oscillator used (See Figure
45.).
7. ICC_FLASH_WRITE operating current while a Flash block write is on going.
