Is there a Macro to return I bit value in status register?

[PG1]

Is there a macro to return the status of the I (global int enable) bit in the status register?

Or do you have to roll your own assembly language function?

Hello,

For 8-bit MCUs there is the function __isflag_int_enabled() that returns the status if the I-bit.  The prototype is within "intrinsics_HC08.h".  There are also similar functions for returning the status of the carry flag, the half carry flag, and the external interrupt pin.

Thanks. I will do a search for it in the HCS08 version of codewarrior, or see if I can port it over.

Hello

Function __isflag_int_enabled() is an intrinsic function of the HC08, HCS08 and RS08 compiler.

If you are targeting another MCU it might not be available.

By the way which MCU are you targeting?
