3.2
Since the ISAC-S TE provides only one interrupt request output (INT), the cause of an interrupt
is determined by the microprocessor by reading the Interrupt Status Register ISTA. In this
register, seven interrupt sources can be directly read. The LSB of ISTA points to eight non-
critical interrupt sources which are indicated in the Extended Interrupt Register EXIR
(figure 42).
