Notes to the DC characteristics
1. The operating supply current is measured with all output pins disconnected;
2. The Idle mode supply current is measured with all output pins disconnected;
3. The Power-down current is measured with all output pins disconnected; XTAL2 not connected;
4. Capacitive loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the low level output
5. Capacitive loading on Ports 0 and 2 may cause the high level output voltage on ALE and PSEN to momentarily fall
