Architectural Overview

The LMI 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 LMI JTAG instructions select the LMI TDO outputs. The
multiplexer is controlled by the LMI JTAG controller, which has comprehensive programming for
the ARM, LMI, and unimplemented JTAG instructions.
System Control and Clocks (Section 6 on page 55)
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.
