Noob question: why equ 1<<0 in barebones tutorial

[Solar]

I must admit that is what I would do. If it was some obscure bit like 27 there might be some point in doing it the other way, but up to about 0x200 I would just write 0x200.

There's where my obsessive-compulsive trait kicks in: If I do it for bit 27, I do it for bit 2 in exactly the same way.

The alternative being writing the integer number plus comment.

0xc0h or $0xC0 that is 11000000b in a bineary value or 196 decimal why, or did you mean the device at that address?
