INTERRUPT MANAGEMENT

Figure 27.

All Interrupt flags (in IFR) except ESPI can be masked in the global interrupt enable register (GIEN).

An Interrupt will be signalled by NINT going low until either the corresponding mask or the flag itself will be reset

by the application software. An autoreset function is available for IFR, allowing to remove all interrupt flags after

reading their state (see SPI).
