Timer 1
The host controls the timer 1 by setting bit CMDRD.STI to start the timer and by writing
register TIMR1 to stop the timer. After time period T1 an interrupt (AUXI.TIN1) is
generated continuously if CNT=7 or a single interrupt is generated after timer period T if
CNT<7
Figure 11
Timer 2
The host starts and stops timer 2 in TIMR2.CNT
is operating in count down mode, for TIMR2.TMD=1 a periodic interrupt AUXI.TIN2 is
generated. The timer length (for count down timer) or the timer period (for periodic timer),
respectively, can be configured to a value between 1 - 63 ms (TIMR2.CNT).
