3.2 System Configuration
The SLIM controls MCU configuration during normal operation and during internal testing. The following
section provides a description of the SLIM configuration registers and their contents.
System configuration registers are used for controlling initial bus configuration, clocking options, I/O port
configuration, and selectively enabling/disabling SLIM submodules to reduce power consumption.
Additionally, the SLIM has a 512-byte (256 word) bootstrap ROM which can be used to configure the
reset and interrupt vectors.
1. Y = M111, where M is the logic state of the module mapping (MM) bit in the SLIMCR.
1. This bit is reserved for future use.
