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.

Writing a '1' will clear the respective flag bit in the SDIFLG register.
Writes of '0' are ignored.

Note: If user writes a '1' to clear a bit on the same cycle that the hardware is trying to set the bit to '1', then hardware has priority and the bit will not be cleared.
