Memory Accelerator Module (MAM) 93 May 03, 2004
Philips Semiconductors Preliminary User Manual
LPC2119/2129/2194/2292/2294ARM-based Microcontroller
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.
*Reset Value refers to the data stored in used bits only. It does not include reserved bits content.
