CCS C Compiler Manual PCB / PCM / PCH

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)

#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
