#19945 - RE: 1 bit operation in C |
Bit instructions ONLY work on sfrs with address ending in 0 or 8 or memory locations 0x20 - 0x2f. '51 compilers that support this will have a data type (for Keil it is bit) that will locate a bit variable in this address space. For a byte where you want to access a single bit there should be a construct (again Keil: bdata) which will locate the byte in the aforementioned space. These are non-ANSI and may thus vary from compiler to compiler.
Have a BIT of fun, Erik |
