It seems like the Lookup function along with PORTA.0(serpin) should work, but the only thing it does is output on pins RB0 and RB1.

Even if I write a simple program to turn on/off the pins, it still keeps addressing pins RB0 and RB1 only.

Am I missing something?

Thanks.

B0 VAR BYTE
serpin VAR BYTE

loop:
For b0 = 0 TO 7
LookUp b0,[0,1,2,3,4,8,16,24],serpin
High PORTA.0(serpin)
Pause 500
Next b0
GoTo loop
