Hi,

This was pointed out to me so I'm passing it along...

In compiling the blink example for the 12F508 it appears to be generating unnecessary code:

- There are "bank select" macros (datahi_xxx, datalo_xxx), but this chip has only one bank of memory.

- There also macros (branchhi_xxx) that are just nop instructions.

The 12F508 has only 512 words of program memory so this seems not good. In a final program size of 47 instructions, 12 of the instructions are unnecessary.

Regards,

Mike
