4
 *   SIM -- System Integration Module
5
 *
6
 * The system integration module (SIM) is used on many Motorola 16-
7
 * and 32-bit MCUs for the following functions:
8
 *
9
 *  () System configuration and protection. Bus and software watchdog
10
 *  monitors are provided in addition to periodic interrupt generators.
11
 *
12
 *  () Clock signal generation for other intermodule bus (IMB) members
13
 *  and external devices.
14
 *
15
 *  () The generation of chip-select signals that simplify external
16
 *  circuitry interface.
17
 *
18
 *  () Data ports that are available for general purpose input and
19
 *  output.
20
 *
21
 *  () A system test block that is intended only for factory tests.
22
 *
23
 * For more information, refer to Motorola's "Modular Microcontroller
24
 * Family System Integration Module Reference Manual" (Motorola document
25
 * SIMRM/AD).
