that is custom$-$developed for a specific application$/$purpose$.$

ii$)$ A memory unit whose locations can be identified using a $\text{'}k\text{'}-$bit address has an

iii$)$ The PC$-$Relative addressing mode offers more flexibility that the Base$+$Offset

addressing mode in its ability to reference any memory location as part of an

instruction.

iv$)$ In LC$-3$ ISA, the Store instructions $($ST$/$STI$/$STR$)$ do not have any impact to the

condition code registers $($N$,$ Z$,$ P$).$
