Figure 8
All five interrupt bits in the ISTA register point at interrupt sources in the Monitor handler
(MOS), C/I handler (CIC), the transceiver (TRAN), the synchronous transfer (ST) and the
auxiliary interrupts (AUXI).
All these interrupt sources are described in the corresponding chapters. After the device
has requested an interrupt activating the interrupt pin (INT), the host must read first the
device interrupt status register (ISTA) in the associated interrupt service routine. The
interrupt pin of the device remains active until all interrupt sources are cleared by reading
the corresponding interrupt register. Therefore it is possible that the interrupt pin is still
active when the interrupt service routine is finished.
Each interrupt indication of the interrupt status registers can selectively be masked by
setting the respective bit in the MASK register.
For some interrupt controllers or hosts it might be necessary to generate a new edge on
the interrupt line to recognize pending interrupts. This can be done by masking all
interrupts at the end of the interrupt service routine (writing FF
and write back the old mask to the MASK register.
