9.5.12 RAM Info Mask Lower Register (RINFOL)
This register is used to select the RAM groups 1 to 32 to run the algorithms selected in the ALGO register.
For an algorithm to be executed on a particular RAM group, the corresponding bit in this register must be
set to 1. The default value of this register is all 1s, which means all the RAM Groups are selected.
Figure 9-17 and Table 9-16 illustrate this register.
The information from this register is used only when bit 0 in OVER register is not set.
