Please anyone explain the meaning of this...

[SBK_SBK_SBK_SBK]

#define testReg8Bits(RegName, GetMask) (RegName & (GetMask))
#define clrReg8Bits(RegName, ClrMask) (RegName &= (byte)(~(byte)(ClrMask)))
#define setReg8Bits(RegName, SetMask) (RegName |= (byte)(SetMask))
#define invertReg8Bits(RegName, InvMask) (RegName ^= (byte)(InvMask))
#define clrSetReg8Bits(RegName, ClrMask, SetMask) (RegName = (RegName & ((byte)(~(byte)(ClrMask)))) | (byte)(SetMask))
#define seqClrSetReg8Bits(RegName, BitsMask, BitsVal) ((RegName &= (byte)~((byte)~((byte)(BitsVal)) & ((byte)(BitsMask)))),\

can anyone please explain the meaning of this............

Can you tell me the part number that you are using? 

this is part of a sample code? Processor expert?

If you look in the other THREE unrelated forums they're posting related questions to, the part is "MC9S08PT8".

I think the "the meaning of this" is that they don't know anything about C programming or the preprocessor. The ProcessorExpert system assumes you have experience with C Programming, the language before being able to use what it produces.

I'd suggest downloading as many App Notes with sample code as you can to get an idea of how these functions are used to make the CPU do what you want. Interrupts are really tricky (you don't call them, they call you).

yes. it is in IO MAP file. i am facing issue with the processor expert.
