Hello ALL I need to access some of the bit positions of the SFR. But each time i tried to declare a variable of the type sbit , i get error C141: syntax error near sbit. I have read the manual and i even tried the statement :
sbit EA = 0xAF
Thanks Erik, I appreciate it. I will read the Bible as suggested. Amos
Only SFRs with addresses that end in 0 or 8 are bit-addressable. Note that there are eight bits in a byte, and the bit addresses for SFR X0 range from X + 0 to X + 7, whereupon you reach SFR X8 with bits X8 + 0 to X8 + 7. There's method in the madness. For registers that are not bit addressable, you can set bits the good old fashioned way, with AND and OR operations. AND / OR also works on the SFRs with addressable bits.
