The #1 in the instruction was specifying that it was testing the second bit from the right. In order to determine even/odd, the rightmost bit is the one that has to be tested.

WebCheck the output of your assembler to see if it emits a short branch whenever possible. If not, you may have to use BRA.S. BSR.S, and Bcc.Sin your source code instead of BRA, BSR, and Bcc. Because a taken short branch is slower than an untaken one, try to avoid taking most branches. http://meseec.ce.rit.edu/eecc250-winter99/250-1-24-2000.pdf
