FREQUENCY OF OPERATION (MHz)
(V_CC=+5V, t_A=25°C)
Normal operation is measured using:
1) External crystals on XTAL1 and 2
2) All port pins disconnected
3) RST=0 volts and EA=V_CC
4) Part performing endless loop writing to internal memory.
Idle mode operation is measured using:
1) External clock source at XTAL1; XTAL2 floating
2) All port pins disconnected
3) RST=0 volts and EA=V_CC
4) Part set in IDLE mode by software.
