Note: In the visible mode, all active interrupt status bits, whether the corresponding
Note: All unmasked interrupt statuses are treated as before.
Please note that whenever polling is used, all interrupt status registers concerned have
to be polled individually (no “hierarchical” polling possible), since GIS only contains
information on actually generated - i.e. unmasked-interrupts.

In FALC
the TAP is a finite state machine (16 states) controlling the different operational modes
of the boundary scan. Both, TAP controller and boundary scan, meet the requirements
given by the JTAG standard: IEEE 1149.1.

actual interrupt is masked or not, are reset when the interrupt status register is
read. Thus, when polling of some interrupt status bits is desired, care must be
taken that unmasked interrupts are not lost in the process.
