WebSep 7, 2024 · Assuming DDR is an 8 bit register, if you wanted to set all bits except the 0 th bit to input mode, you could write 1: 1. DDR = 0x01; // set bit zero to output mode. If sometime later you wanted to also set the 1 st and 2 nd bits to output mode while keeping everything else intact, the easy way to do it is simply to OR the bits you want: 1. WebDec 18, 2016 · The reserved bits are so that the protocol can gain additional features in the future. This happens every once in a while. For example, off the top of my head I know that the original IPv6 multicast protocol ( RFC 3306) called for four flag bits ( 00PT ), the first two of which were reserved.

First, you should NOT write randomly into it lest your code becomes un-portable. What happens when the architecture assigns a new meaning to the reserved bits in future?

With a 1-byte opcode (8 bits), that leaves 32-8 = 24 bits for the address. (2) Think of memory as a collection of post office boxes, all of the same size. If each box was 1 byte in size, then one box number would get you one byte. WebOct 14, 2015 · The inverse of 2^x is log (x)/log (2) so to get the number of bits for 22 addresses, you just do: log (22)/log (2) = 4.459 Obviously you can't do decimal prefix length so you have to round that up to the closest integer, which is 5. You need 5 bits, or 32-5 = 27, i.e. a /27 network! Share Improve this answer Follow edited Nov 26, 2015 at 23:59 simply marvelous peppered cow nz
