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 9-16 and Table 9-15 illustrate this register.
