Is the balance available immediately after selling SME stock?

Is the balance available immediately after selling SME stock?
Suppose, I sell 1 SME stock (1 lot = 90K), will 90K be immediately available to trade or it will be 80% today and 20% the next day? I know we now get 100% amount after selling ordinary shares but what happens in case of SME stocks?

@ShubhS9

Even for selling SME stocks, you will get 100% of the sale proceeds.

on the same day or the next day?
Also, what are unsettled SME stocks? and why are they not settled on the same day?
