I need a good 64 bit assembly book for beginners, can you recommend one, I'm kinda short on cash so I can only afford one. I have a few 32 bit books like -Linux assembly, high level assembly, and peter nortons assembly but I got to admit they aren't very good. I want to play around with...

I want to know the best tally for MCNP Flux (avg and for each assembly) Please help

I have an example given in the textbook that defines port A bits 5 as PA5 equ 0x40004080. Port A is 0x40004000, and the first 7 bits are for data. I do not see how bit 5 is 0x80. I figured that would be bit 7 and bits 5 would be 0x20. We use ARM assembly language for LM4F120H5QR microcontroller.
