+/**
+ * The M16c/62p hardware timer configuration used by Mulle.
+ * 
+ * STOP MODE ENABLED:
+ *   TB0 bridges its tics from the RV8564 to TB2 in TMilli speed.
+ *   TA0 and TA1 are used to create a 32 bit counter. TA0 counts
+ *   tics from TB2 and TA1 counts TA0 underflows.
+ *   TB0 and TB1 are used to create a 32 bit Alarm. TB0 counts
+ *   tics from TB2 and TB1 counts TB0 underflows.
+ *
+ * STOP MODE DISABLED:
+ *   TA0 generates TMilli tics.
+ *   TB0 generates TMilli tics.
+ *   TA1 is a 16 bit counter that counts tics from TA0.
+ *   TB1 is a 16 bit alarm that counts tics from TB0.
+ *
+ * ALWAYS USED:
+ *  NOTE: Counter timers are turned off when the mcu goes into stop mode.
+ *   TA3 generates TMicro tics.
+ *   TA2 is a 16 bit TMicro counter that counts tics from TA3.
+ *   TA4 is a 16 bit TMicro alarm that counts tics from TA3.
+ *      TB3 is a 16 bit Radio counter.
+ *   TB4 is a 16 bit Radio alarm.
