oscillator requires very little bias current.
- External oscillator: Crystal, RC, C, or CMOS Clock
- SmaRTClock oscillator: 32 kHz Crystal or internal
- Can switch between clock sources on-the-fly; useful
in implementing various power saving modes
On-Chip Debug
- On-chip debug circuitry facilitates full-speed, non-
intrusive in-system debug (no emulator required)
