Hello,

What do these two instructions ?

A description like 'jump if Port interrupt high' that can be found in the prog manual isn't really clear for me.

Thank you

These 2 instructions are not used. In fact, the interrupt line is an

internal CPU interrupt line whose state is completely different

depending on the considered device.

These 2 instructions will be suppressed for the next ST7 generation, but have been kept in ths ST7 programming manual for historical reason (1 client uses them).
