MAM CONFIGURATION

After reset the MAM defaults to the disabled state. Software can turn memory access acceleration on or off at any time. This
allows most of an application to be run at the highest possible performance, while certain functions can be run at a somewhat
slower but more predictable rate if more precise timing is required.

REGISTER DESCRIPTION

All registers, regardless of size, are on word address boundaries. Details of the registers appear in the description of each
function.
