Freescale Semiconductor
NOTES:
1. Affects high voltage entry to monitor mode only (SW2 at position C):
2. SW2: Position C — High-voltage entry to monitor mode.
3. SW3: Position E — OSC1 directly driven by external oscillator.
SW2: Position D — Low-voltage entry to monitor mode (with blank reset vector).
See
SW3: Position F — OSC1 driven by crystal oscillator circuit.
