I want to use global bit and I read the document which was in tutorial.We had had to declare .bit section in link file.But how to prepare to link file

example my link file is

+seg .text -b 0xfa00 -n .text # program start address

+seg .const -a .text # constants follow code

+seg .bsct -b 0x80 -m 0x80 # data start address

+seg .ubsct -n iram # uninitialized zero page

#

# define the .share segment when using compact or memory models only

#

+seg .share -a iram -n share -is # shared segment

Where and how should I allocate .bit section and which address if it is possible???Can you help me?And Is ıt required identifier such as extern like global variables?

example of C file:

_Bool mybit; // general bit variable, requires the .bit segment to be declared in the linker file

_Bool PA0@PADR:0; // absolute bit variable, does not require the .bit segment

....

mybit=0;

my_global_var=0;

while(1)

{

PA0=0;

PA0=1; // Generate a waveform

if (my_global_var==1)

printf(''Interrupt happened!\n'');

}

and the associated linker file

+seg .text -b 0xf000 -n .text # program start address

+seg .const -a .text # constants follow code

+seg .bsct -b 0x80 -m 0x80 # data start address

+seg .ubsct -n iram # uninitialized zero page

#

# define the .share segment when using compact or memory models only

#

+seg .share -a iram -is -n .share # shared segment

+seg .bit -a .share # bit segment after the share segment (still in page zero)

+seg .eeprom -b 0xc00 -m256 # eeprom segment

.....

the bit segment must be in page 0.

Thank you very much Luca

I use stvd3 and cosmic,but i do nothing with *.lkf file,I just click

''project''--''setting''--''linker''--''input''--''Zero Page'' then ''add Section'' then write ''.bit''; all is ok.

it is so easy.

maybe it will be helpful for you.

I am a chinese,sorry for my poor english level
