Register Array Variables
i,j,k,l,m,nWhen these variables are used in a register name, an offset, or an address, they refer to the value of a register array where the register is part of a group of repeating registers. The register groups form a hierarchical structure and the array is represented with a formula.
yWhen this variable is used in a register name, an offset, or an address it refers to the value of a register array.
