 ===== Firmware =====
 A computer program that is held in non-volatile memory such as EPROM or flash memory. A PIC processor has a small amount of RAM used for variables and a much larger flash memory for program.
+=====Flag=====
+A 'Flag' is a single [[glossary_b#bit|'Bit']] of information that can either be 'True', 'On', 'Set' (1) or 'False', 'Off', 'Clear' (0). Flags most often are in sets of 8 [[glossary_b#byte|(a Byte)]] but not always.
+As an example, in the CANACC8, one of the first [[glossary:glossary_c#cbus|CBUS]] modules, each learnt event has two EVs (Event Variables), these are actually 'Flag Bytes' and each 'Bit' is directly associated with one of the outputs. In the first byte if a 'Bit' or 'Flag' is set (1) then that event acts on the corresponding output, an ON event will switch the output on, an OFF event will turn it off. The second byte contains the 'Polarity Flags' these only have meaning if the matching flag in the first byte is set and have the effect of inverting the action performed on the output. So if say bits 0 & 1 are set in the first byte and bit 1 is set in the second the result will be that an On event will switch output 1 on and output 2 off.
+===== Flash Memory =====
+[[wp>/Flash_memory|Flash Memory]] is an electronic (solid-state) non-volatile computer storage medium that can be electrically erased and reprogrammed.
