• The host loses contact with the monitor while the program is run-

ning and it enters an Interrupt Service Routine when nesting is

turned on.

• The host cannot halt with the debugger's Debug, Halt command if

global IRQ enable is disabled; however, breakpoints will work.

Command Processing

Command processing, initiated from either the UART ISR or the Halt

loop, is done in the command-processing kernel. This kernel parses the

commands and executes the instructions. If the instruction requires data

to be sent back to the host, the kernel initiates the response.

The ability to stop the execution of code and examine processor registers

and memory is extremely helpful when debugging code. Note that the

debugger automatically inserts breakpoints at the function

the Settings, Run To Main command is checked, and at the

instruction.

The monitor does not initialize the AD73322 codec. This provides you

with greater flexibility to experiment with custom codec operations. Sim-

ple code examples, such as TalkThrough, are provided with your EZ-KIT

Lite to demonstrate some basic codec operations. It is recommended that

you model your code using these examples.

Once the codec has been initialized, you must use a hard reset to

re-initialize it.
