logic resets this bit again automatically after 4 BCL clock cycles. The address range of
the registers which will be reset at each SRES bit is listed in
3.2.5
The ISAC-SX provides two timers which can be used for various purposes. Each of them
provides two modes
only once after expiration of the selected period, and a periodic timer interrupt, which
means an interrupt is generated continuously after every expiration of that period.

When the programmed period has expired an interrupt is generated and indicated in the
auxiliary interrupt status ISTA.AUX. The source of the interrupt can be read from AUXI
(TIN1, TIN2) and each of the interrupt sources can be masked in AUXM.
