4.3 Interrupt Interface

Special events in the HSCX are indicated by means of a single interrupt output, which requests

the CPU to read status information from the HSCX, or, if Interrupt Mode is selected, transfer

data from/to HSCX.

Since only one INT request output is provided, the cause of an interrupt must be determined

by the CPU reading the HSCX’s interrupt status registers (ISTA, EXIR).

The structure of the interrupt status registers is shown in figure 20.
