Post by thread:12 Bit signed compare. HELLLPPPPPP.

I am having trouble in writing code for the PIC16C71 to compare two 12bit 'signed' numbers. Once the comparison is done I need to save the lesser of the 12bit number, for example; LOADA word1 ;get 12 bit signed value into acca CMPA word2 ;compare word1 to word2 BLE savewd1 ;if word1 << word2 then save word1 STORA word2 ;if word1 >> word2, save word1 -> word2 RETN savewd1: STORA rseln ;save word1 value RETN Excuse the mnemonics chosen. I hope that its clear as to what I need to do. Any pointers would be appreciated.
