/**
 * Notes:
 *   * The functionality of TASK_SHUTDOWN is a bit of a guess
 *   * INTENCLR will always read as 0
 *   * Unlike in real HW, tasks cannot occur simultaneously, they always happen in some sequence
 *     so task priority is not accounted for
 *
 * Implementation notes:
 *
 * In Timer mode, the timer is not actually counting all the time, but instead
 * a HW event timer is programmed on the expected matches' times whenever the
 * timer is started, stopped, or the compare values are updated.
 *
 * In Count mode, the timer count value (Counter[t]) is updated each time the
 * corresponding TASK_COUNT is triggered.
