Lua 5.3 so ce 6.5+ added bitwise operator, so

For individual bit:
it is something show as is
Code:

a = readInteger(addr)
print((a >> 3)  & 0x01)


For bit field, ie. bit length,bn > 1 with start bit num, bs

something like:
Code:

print((a >> bs) & ((1<<bn) -1))



For ce 6.4, there are a set of bitwise function , bShr, bAnd, bXor ... etc.


bye~
