If the core is the same as the 8051 except for the SFRs, you should be able to 
use the existing 8051 target. You would only have to provide the SFRs 
specific to the CC1110 in an include file.

Good luck!

Pravin,

To use this mcu the first step I recommend is to create a header 
file for it with the SFR definitions. Make sure to create an alias 
for MPAGE with the name that SDCC expects: _XPAGE. You can use 
cc2530.h that comes with SDCC as a template. We would welcome it if 
you would give this header file in return to our community for 
inclusion in SDCC.

Then when linking use the option --xram-loc 0xF000 and maybe --xram-
size and --code-size.

Greets,
Maarten

Hello Pravin,

Thanks for the header file. I have added it to SDCC.

I can't see anything wrong with your program except that 
it might take a long time (>1 min) for the led to blink. 
That is assuming that the LargeWait can count 
milliseconds as it claims. But that is completely 
dependent on your clock frequency.

Greets,
Maarten
