#186839 - 16 bit vs 8bit signed compare |
Hello..
How I can test 16 bit signed integer in asm. Ie I have r0 as MSB and r1 as LSB and want to test if its greater against Acc. The r0/r1 pair is signed 16 bit and Acc is signed 8 bit. Probably need to extend Acc to 16 bits (not problem) but how to perform test to be borrect in all -+ cases? |
