You can use "bdata"
char bdata bitByte; X = bitByte ^ 6; That's a common mistake (been there, done that) The '^' used as an operator in an expression like that has its normal, standard 'C' meaning of "Exclusive-OR" To define a bit within a bit-addressable byte, you need to do this: char bdata bitByte; // Define a bit-addressable byte sbit X = bitByte^6; // Define 'X' as bit 6 within the bytehttp://www.keil.com/support/m...ddrobj.htm Why on earth Keil had to choose '^' for this purpose - thus almost guaranteeing this confusion - is a mystery! |
