/**
 * 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.
