Five interrupt indications can be read directly from the ISTA register and another six interrupt
indications from the extended interrupt register (EXIR).
After the HSCX has requested an interrupt by setting its INT pin to low, the CPU must first read
the interrupt status register of channel B (ISTA-B) in the associated interrupt service routine.
The three lowest order bits (bit 2-0) of ISTA-B (ICA, EXA, EXB) point are set to those registers
in which the actual interrupt source is indicated. It is possible that several interrupt sources are
indicated referring to one interrupt request (e.g. if the ICA bit is set, at least one interrupt is
indicated in the ISTA register of channel A).
An interrupt source from channel B is implicitly indicated by bits 7-3 of ISTA-B; therefore these
bits must also always be checked.
The INT pin of the HSCX remains active until all interrupt sources are cleared by reading the
corresponding interrupt register. Therefore it is possible that the INT pin is still active when the
interrupt service routine is finished.
For some interrupt controllers or CPUs 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
H
into the MASK register) and write back the old
mask to the MASK register.
The HSCX interrupt sources can be logically grouped into
– receive interrupts,
– transmit interrupts, and
– special condition interrupts.
Each interrupt indication of the ISTA registers can be selectively masked by setting the
respective bit in the MASK register.
The following tables give a complete overview of the individual interrupt indications and the
cause of their activation as well as specific restrictions (marked with ’’*’’
).
