9.5.11 ROM Algorithm Mask Register (ALGO)

This register is used to indicate the algorithm(s) to be used for the memory self-test routine. Each bit

corresponds to a specific algorithm. For example, bit 0 controls whether algorithm 1 is enabled or not.

Figure 9-17 and Table 9-16 illustrate this register.
