Co control word

Question

The control field of a microinstruction supports 2 groups of control signals in which G1 indicates none or one of a 256 control signals and G2 indicates atmost 6 signals from the remaining. 

What is the size of the control field in the instruction?

Comments

@hitendra singh see that 256 bits are reserved for the vertical signals .. and from the remaining means other signals and you cannot use that from remaining 256 signals.. read it carefully... 

from the question : it will have total 256+6 cs = 262 signals where 256 are fixed for vertical and 6 for horizontal...

@Satbir yes bro each bit will represent a signal in horizontal mic prog..

I think question  is little bit wrong question says that 

2 groups of control signals in which G1 indicates none or one of a 256 control signals and G2 indicates atmost 6 signals from the remaining .

 G2 indicates atmost 6 signals from the remaining .What do you think from the word remaining ?

I think remaining means 255.

Although i get it what you have suggested but at least give it a thought.

G2 indicates atmost 6 signals from the remaining  

These are 2 different statements. remaining could be anything but we have to be concerned with only 6 signals that are mentioned for G2.
