PreProcessor The compiler will set the access bit depending on the value of the file register. If there is just a variable identifier in the #asm block then the compiler inserts an & before it. And if it is an expression it must be a valid C expression that evaluates to a constant (no & here). In C an un-subscripted array name is a pointer and a constant (no need for &). #bit Syntax: Elements: #BIT id = x.y id is a valid C identifier, x is a constant or a C variable, y is a constant 0-7 Purpose: A new C variable (one bit) is created and is placed in memory at byte x and bit y. This is useful to gain access in C directly to a bit in the processors special function register map. It may also be used to easily access a bit of a standard C variable. Examples: #bit T0IF = 0x b.2 ... T1IF = 0; // Clear Timer 0 interrupt flag int result; #bit result_odd = result.0 ... if (result_odd) Example Files: Also See: ex_glint.c #BYTE, #RESERVE, #LOCATE, #WORD #build Syntax: Elements: #BUILD(segment = address) #BUILD(segment = address, segment = address) #BUILD(segment = start:end) #BUILD(segment = start: end, segment = start: end) #BUILD(nosleep) segment is one of the following memory segments which may be assigned a location: MEMORY, RESET, or INTERRUPT 95
