104 * when it's not "external") is silicon-specific. AT91 platforms use one
105 * set of definitions; AVR32 platforms use a different set. Don't hard-wire

108 * the 32 KiHz clock.

110 * The timers can be chained in various ways, and operated in "waveform"
111 * generation mode (including PWM) or "capture" mode (to time events). In
112 * both modes, behavior can be configured in many ways.
113 *
114 * Each timer has two I/O pins, TIOA and TIOB. Waveform mode uses TIOA as a
115 * PWM output, and TIOB as either another PWM or as a trigger. Capture mode
116 * uses them only as inputs.
