NOTES:
1. High Impedance Output
2. Current IDDPLL = 1mA (Colpitts Oscillator)
3. Current IDDPLL = 3mA (Pierce Oscillator)
4. High Impedance Output
5. Monitors V_DDA, active only in Full Performance Mode. Indicates I/O & ADC performance degradation due to
low supply voltage.
6. Monitors V_DD, active only in Full Performance Mode. V_LVRA and V_PORD must overlap
7. Monitors V_DD. Active in all modes.
NOTE: The electrical characteristics given in this section are preliminary and
should be used as a guide only. Values in this section cannot be
guaranteed by Motorola and are subject to change without notice.
