Hi, Looking in the code generator it seems that __interrupt should turn a normal function into an ISR and generates some PUSHes/POPs and a RETI. But it also seems that unless you make it callee-saves it forgets half of the registers.
If the __interrupt function is also __critical it will use RETN for the NMI. Unfortunately there is no implementation for generation of the Interrupt Vector Table (IVT) in SDCC for the Z80. Interrupts are also not tested in the regression tests for Z80 (critical.c/interrupt.c).
