Hello!
Why this statement "OPTION_REG = 0xC5;" is ok when I am writing to OPTION_REG register, but when I am using the next statements I get an error ?
"RBPU not a member of a struct/union"

OPTION_REGbits.RBPU = 0;
OPTION_REGbits.INTEDG = 0;
OPTION_REGbits.T0CS = 0;
OPTION_REGbits.T0SE = 0;
OPTION_REGbits.PSA = 0;
OPTION_REGbits.PS2 = 0;
OPTION_REGbits.PS1 = 0;
OPTION_REGbits.PS0 = 1;

I also trying OPTION_REGbits.NOT_RBPU = 0;

 

What are the register bits defined/described as in the definition .INC file?
Max.

 

Look in the .h file for the 877A to see how that bit is defined.

 

Which compiler are you using?

 

I looked in the header file for PIC16F877A, and RBPU is defined as nRBPU.
Now the program works.
I am using HI TECH compiler.
Thank you guys !
