The MSC8113 has two mechanisms for writing the reset configuration:
Fourteen signal levels (see Chapter 1 for signal description details) are sampled on
Configuration Mode and boot and operating conditions:
Freescale Semiconductor
Configuration pins sampled (Refer to
Section 2.5.4.1 for details).
SPLL state reset
System reset configuration write through
the DSI
System reset configuration write though
the system bus
HRESET driven
SIU registers reset
IPBus modules reset (TDM, UART,
Timers, DSI, IPBus master, GIC, HS, and
GPIO)
SRESET driven
SC140 extended cores reset
MQBS reset

Through the direct slave interface (DSI)
Through the system bus. When the reset configuration is written through the system bus, the MSC8113 acts as a
configuration master or a configuration slave. If configuration slave is selected, but no special configuration word is
written, a default configuration word is applied.
