Stellaris^® LM3S818 Microcontroller
1.4.7.2
1.4.8
The Stellaris JTAG controller works with the ARM JTAG controller built into the Cortex-M3 core.
This is implemented by multiplexing the TDO outputs from both JTAG controllers. ARM JTAG
instructions select the ARM TDO output while Stellaris JTAG instructions select the Stellaris TDO
outputs. The multiplexer is controlled by the Stellaris JTAG controller, which has comprehensive
programming for the ARM, Stellaris, and unimplemented JTAG instructions.
System Control and Clocks (see page 153)
System control determines the overall operation of the device. It provides information about the
device, controls the clocking of the device and individual peripherals, and handles reset detection
and reporting.
