the interrupt pending flag can be read via RR0.Bit1 of channel A only
No info if the The DART/SIO interrupt signal is known to be connected to the CPC hardware, probablyon the original Amstrad CPC serial interface.It is unknown if this is the case on the later revision or 3rd party interfaces. Usage of native Z80 peripheral interrupts is complicated by their knowledge of CPU interrupt acknowledge signals which conflict with the Gate Array interrupts. A workaround is documented in the firmware guide appendix 13. it isn't?
